Consider the Converse of Isosceles Triangle Theorem.

AJ≅ AL

Practice makes perfect

Before we begin, let's use the given information to mark the congruent angles of the given figure.

To name two congruent segments, we will use the following theorem.

Converse of Isosceles Triangle Theorem
If two angles of a triangle are congruent, then the sides opposite those angles are congruent.

Using this theorem, let's show the congruent sides.

We can see that AJ is congruent to AL. AJ≅ AL
