In an isosceles triangle, what is true about the sides and angles?

In an isosceles triangle, two sides are of equal length, and the angles opposite these sides are also equal. This property signifies that if two angles in a triangle are congruent (or equal), the sides opposite those angles must also be congruent. Therefore, the statement about sides opposite congruent angles being congruent accurately describes this fundamental characteristic of isosceles triangles.

In general, the congruence of angles leads to the congruence of the corresponding sides in such triangles, which is a key principle in triangle properties. The nomenclature and labeling in geometry often highlight this aspect, reinforcing why this statement holds true in the context of isosceles triangles.
