in the figure below, ABC is a triangle in which AB=AC. X and Y are points on AB and AC such that AX=AY. prove that triangle ABY congruent to triangle ACX
given: in the triangle ABC, AB = AC and AX = AY
TPT:
proof:
in the triangles
AX = AY and
AC = AB
∠A is common.
therefore by SAS congruency triangles are congruent.
hope this helps you.
cheers!!
