Looking at the worksheet, it’s titled “A Closer Look: Isosceles & Equilateral Triangles” and includes a “Practice” section with 6 problems. Since you didn’t specify which problem to solve, I’ll assume you want help with
Problem 1, as it’s the first one shown.

Problem 1:
We are given an isosceles triangle with two sides labeled 12 cm each, and the base labeled 10 cm. We’re asked to find the perimeter.
Step 1: Understand what an isosceles triangle is.
→ It has two equal sides (called legs) and one different side (called the base).
Step 2: Add up all three sides.
→ Perimeter = side + side + base
→ Perimeter = 12 cm + 12 cm + 10 cm
Step 3: Do the math.
→ 12 + 12 = 24
→ 24 + 10 = 34
So, the perimeter is 34 cm.
✔ Double-check: Two equal sides (12 each), plus base (10). 12+12+10=34. Correct.
Final Answer:
34 cm
