### Prove that the sides opposite to equal angles of a triangle are equal.

**Answer:**

**Step by Step Explanation:**

- Let ^@ ABC^@ be an isosceles triangle with ^@\angle B = \angle C.^@
- We need to prove that ^@ AB = AC ^@
- Let us construct an angle bisector ^@AD^@ of angle ^@A.^@
- As the corresponding parts of congruent triangles are equal, we have @^ AB = AC. @^
- Thus, the sides opposite to equal angles of a triangle are equal.
