What is SAS congruence theorem
SAS congruence theorem states that: If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.
The included angle in this case is the right triangle.
CPCTC (Corresponding Parts of Congruent Triangles are Congruent): asserts that if two triangles are congruent, then their corresponding parts (angles and sides) are congruent.
hence we can say that: Segment FH is congruent to Segment GE
