IM Geo.2.7 Practice: Angle-Side-Angle Triangle Congruence

Autor:GeoGebra Classroom Activities, IM Algebra 1, Geometry, Algebra 2

What triangle congruence theorem could you use to prove triangle is congruent to triangle ?

Han wrote a proof that triangle BCD is congruent to triangle DAB.

Han's proof is incomplete.

Line is parallel to line and cut by transversal . So angles and are alternate interior angles and must be congruent.
Side is congruent to side because they're the same segment.
Angle is congruent to angle because they're both right angles.
By the Angle-Side-Angle Triangle Congruence Theorem, triangle is congruent to triangle

How can Han fix his proof?

Segment GE is an angle bisector of both angle HEF and angle FGH.

Prove triangle is congruent to triangle .

Triangles ACD and BCD are isosceles.
