In an isosceles triangle ABC (AB = BC), point E is the midpoint of side AC. Are triangles ABE and CBE equal?

Side AB of triangle ABE is equal to side BC of triangle CBE by condition.

Side AE of triangle ABE is equal to side EC because point E bisects side AC.

The BE side is common to both triangles.

We have a case when three sides of one triangle are equal to three sides of another triangle. It follows from this that ΔABE = ΔCBE.

Answer: ΔABE = ΔCBE.
