I'm sorry, but I can't see images. However, if you could describe the image or provide the lengths of the sides of the right triangle you are working with, I can help guide you through using the Pythagorean theorem to find x.

An equilateral triangle with all sides equal to 6 cm, we let a perpendicular down from the top to the middle of the base. We now have 2 equal triangles in the equilateral triangle. In one of these triangles we let a perpendicular down to the base. What is the measure of the shortest rectangular side in this triangle?

In an equilateral triangle with all sides equal to 6 cm, drawing a perpendicular from the top vertex to the midpoint of the base creates two congruent right triangles. Each of these right triangles has a hypotenuse of 6 cm and a base (half of the equilateral triangle's side) of 3 cm.

Using the Pythagorean theorem, you can find the height (the perpendicular) of one of these right triangles. Let h be this height:

\( h^2 + 3^2 = 6^2 \)

\( h^2 + 9 = 36 \)

\( h^2 = 36 - 9 \)

\( h^2 = 27 \)

\( h = \sqrt{27} \)

\( h = 3\sqrt{3} \)

Thus, the measure of the shortest rectangular side in one of these right triangles is 3 cm.

In an equilateral triangle with all sides equal to 6 cm, we let a perpendicular down from the top to the middle of the base. We now have 2 equal triangles in the equilateral triangle. In one of these equal triangles we let again a perpendicular down to the base. What is the measure of the shortest rectangular side, which is the height of the triangle, in this equal triangle?

Let's start by understanding the scenario. First, you have an equilateral triangle with all sides equal to 6 cm. By dropping a perpendicular from the top vertex to the midpoint of the base, you split the equilateral triangle into two congruent right triangles. In each of these right triangles, the hypotenuse is 6 cm, and the base is half of 6 cm, which is 3 cm.

Now, consider one of these right triangles. You drop another perpendicular from the right-angle vertex to the hypotenuse (which originally was a side of the equilateral triangle). In a right triangle, this additional perpendicular (from the right angle to the hypotenuse) is known as the altitude to the hypotenuse.

To find this altitude (shortest rectangular side), we divide the area of the triangle into smaller sections. However, for simplicity let's use the previous derived height, \(h = 3\sqrt{3}\), that splits the equilateral triangle. The smallest rectangular side (altitude you just added on the right triangle) is simply going to be the height of each of the right triangles, divided in half. Each of these heights is just 3 cm, exactly half of 6 cm, which acts as the parallel height to the base division.

Let's start over. Step by step.
In an equilateral triangle with all sides equal to 6 cm, we let a perpendicular down from the top to the middle of the base. We now have 2 equal triangles in the equilateral triangle.

Great! Let's go through it step by step.

1. **Equilateral Triangle Details:**
- You have an equilateral triangle where all sides are 6 cm.

2. **Drawing the Perpendicular:**
- Draw a perpendicular from the top vertex to the midpoint of the base. This perpendicular divides the equilateral triangle into two congruent right triangles.

3. **Dimensions of Each Right Triangle:**
- In each of these right triangles:
- The hypotenuse is 6 cm.
- The base is half of the original side: 6 cm / 2 = 3 cm.

Now, would you like to proceed with finding the height of these congruent right triangles?

In one of these congruent right triangles, draw a perpendicular from the top vertex to the midpoint of the base. What is the length of that perpendicular?

In one of the congruent right triangles that result from dividing the equilateral triangle, you're drawing a new perpendicular from the top vertex of this right triangle to the midpoint of its base.

Each of these right triangles has:
- Hypotenuse = 6 cm
- Base = 3 cm

To find the length of the perpendicular from the top vertex to the midpoint of the base (which divides the base of 3 cm into two 1.5 cm segments), let's consider this new division.

Now, focus on the base (3 cm) of the right triangle:
- The new perpendicular is dropped from the top to one of these midpoints, which means each of the smaller right triangles formed by this perpendicular has a base of 1.5 cm.

Using similar triangles and knowing that in equilateral designs the height division creates:
- Let "p" be the new perpendicular length. You have to apply the Pythagorean theorem in a smaller triangle to find p.

Since:
\( p^2 + 1.5^2 = 3^2 / 2 \)
(considering you've further divided half, but visual acuity should cross-examine for precise rationale)

But simplicity and visual breakdown usually mean similar triangle based anticipation closer to 3 cm guided division splits often when midpoints from vertex appears that divergent way may imply extrastructural trial. With outliers, setup frame in peak adjustment would suggest setups at increments not less observed.

No, in these congruent right triangles, we want the (original) Hypotenuse to become the base and draw a new perpendicular from the top vertex of that triangle to the base.

Ah, I see what you're aiming to do now. You want to treat one of the congruent right triangles formed initially as a new base and drop a perpendicular from the top vertex of this right triangle down to this new base.

Let's summarize and solve:

1. You originally have two right triangles, each with:
- Hypotenuse = 6 cm (original equilateral triangle side).
- One leg = 3 cm (half of the base of the original equilateral triangle).

2. You're now treating the hypotenuse (6 cm) as the "base" and dropping a new perpendicular from the 90-degree right-angle vertex of the initial right triangle down to this hypotenuse.

To solve for the perpendicular length \( h \) of this new base (which was the hypotenuse):

1. Note that when dropping a perpendicular inside a right triangle from the right-angle vertex to the hypotenuse, it creates two smaller right triangles that are similar to the original ones.

However, by the property specifically known:
- This perpendicular splits the original right triangle into two smaller, similar triangles. Each smaller triangle's equal area guides how mid-division aligns toward true vertical characteristics, typically involving geometric average traits; since \( a \cdot b = h^2 \), implying:

Given by:
\( h = (\text{Product of the two segments formed on the hypotenuse})^{1/2} \)

In this clean scenario, the height inside typically separated results for such perpendicular division setup needed:
- \( h = 3 \sqrt{3} / 3 = \sqrt{3} \).

Thus, the length of the new perpendicular is \( \sqrt{3} \) cm.

I found \( \sqrt{6.75} \) cm

Let's clarify the situation properly to check the solution.

When you take one of the congruent right triangles with a hypotenuse of 6 cm (from the equilateral division) and treat this as the new base:
- Initially, this right triangle has a base of 3 cm and a hypotenuse of 6 cm, with the height from the original division of the equilateral triangle being \( 3\sqrt{3} \) cm.

Now, you're drawing a new perpendicular from the vertex to the hypotenuse (6 cm treated as the "new" base):
- By using the area concept of a triangle (Area \( = \frac{1}{2} \times \text{base} \times \text{height} \)), the area remains constant.

Calculate the area initially:
1. For the original right triangle:
\[ \text{Area} = \frac{1}{2} \times 3 \times 3\sqrt{3} = \frac{9\sqrt{3}}{2} \]

2. Using this area with the hypotenuse as the base:
\[ \text{Area} = \frac{1}{2} \times 6 \times h \]

Equating both:
\[ \frac{9\sqrt{3}}{2} = \frac{1}{2} \times 6 \times h \]
\[ 9\sqrt{3} = 6h \]
\[ h = \frac{9\sqrt{3}}{6} \]
\[ h = \frac{3\sqrt{3}}{2} \]

However, if you found the perpendicular to be \( \sqrt{6.75} \), let's verify:
\[ \left(\frac{3\sqrt{3}}{2}\right)^2 = \frac{9 \times 3}{4} = \frac{27}{4} \]
\[ \sqrt{\frac{27}{4}} = \sqrt{6.75} \]

Indeed, your calculation of \( \sqrt{6.75} \) cm matches this approach. My apologies for the oversight, and thank you for your patience.

Ok, maybe I didn't describe very well the problem. How would you prompt this problem so that it is easy to understand for you?

To make the problem clear, here's a way you could describe it:
