alleryWhy is AAS equivalent to ASA for triangle congruence?
ATriangles share a side
BOpposite angles match
CAll angles sum to 180°
DExterior angles match
Answer & Solution
Correct answer: C. All angles sum to 180°
Given any two triangle angles, the third angle is uniquely fixed because all angles sum to 180°.
