The image shows a triangle labeled \( \triangle JKL \) with the following given measurements:

- \( \overline{JL} = 16 \)
- \( \overline{JK} = \overline{KL} = 18 \)
- \( \angle J \) and \( \angle L \) are the base angles, indicating that this is an isosceles triangle since two sides (\( \overline{JK} \) and \( \overline{KL} \)) are equal.

To find the measure of side \( \overline{KL} \), you don't need to calculate anything since it is directly given as 18 units. Therefore, the length of \( KL = 18 \).

Let me know if you'd like more details or have additional questions!

Here are some questions to explore the topic further:

1. How can the Pythagorean theorem be applied to an isosceles right triangle?
2. What is the general formula for finding the height of an isosceles triangle?
3. Can we calculate the area of this triangle using the given side lengths?
4. How do the properties of an isosceles triangle affect the base angles?
5. What would change in the problem if \( \overline{JL} \) and \( \overline{KL} \) had different lengths?

**Tip:** When solving problems involving isosceles triangles, remember that the base angles (those opposite the equal sides) are always congruent!

Find the measure of KL in the isosceles triangle JKL where JK = KL = 18 and JL = 16.
