Question

PLEASE HELP


Which postulate or theorem proves that these two triangles are congruent?

A. ASA Congruence Postulate
B. SAS Congruence Postulate
C. HL Congruence Theorem
D. AAS Congruence Theorem

I think it's either A or D.

Answer 1

A AsA  the angle a and d are equal and side ae and de are egual and angles e are equal

Answer 2

Answer:

A. ASA Congruence Postulate

Step-by-step explanation:

We have marked that ∠BAE and ∠CDE are congruent.  We also have marked that AE and ED are congruent.  

∠AEB and ∠CED are also congruent; this is because they are vertical angles.  Vertical angles are opposite angles that share only a vertex; these are vertical angles and thus are congruent.

This gives us two angles and an included side; this gives us ASA.
