Question

What else would need to be congruent to show that ΔJKL ≡ ΔMNO by AAS?

__ __
A) LK ≡ ON

B) ∠K ≡ ∠N
__ __
C) LK ≡ OM

D) ∠L ≡ ∠O

Answer 1

Following the given steps :

1. Since two corresponding angles are equal, the triangles are similar and angle B = angle Y.

2. Now you can you can use ASA on (angle B, angleC, side BC) and (angle Y, angle Z, side YZ)

From step 1
- C is true and doesn't need to be given;
- D was explicitly given as true.
