Question

Given: JS ≅ KS; ∠1 ≅ ∠8; ∠2 ≅ ∠7

Which postulate justifies that ΔJAS ≅ Δ KCS?
A) AAS CORRECT ANSWER
B) ASA
C) SAS
D) SSS

Answer 1

AAS

Explanation:

Two corresponding angles and a non-included side are given as being congruent.

I also just answered this question and got it right

Answer 2

Triangle ΔJAS:
we know side JS, angle 1 and angle 2

Triangle ΔKCS:
we know side KS, angle 7 and angle 8

For each of these triangles we know one side and two angles.

In the possible answers A stands for angle and S stands for side.
So the correct answer would be something that involves one S and two As. That could be either a) or b). We choose a) because we have two angles and a side opposite to one of them. We would choose b) if the side was between these two angles.
