Question

what is the missing statement in this proof?

Explanation:

Step1: Analyze the SAS criterion

The SAS (Side - Angle - Side) criterion for congruence requires two sides and the included angle to be equal. We have \(WA = YA\), \(XA = ZA\) (from step 2) and \(\angle YAZ=\angle XAW\) (from step 3).

Step2: Identify the congruent triangles

The two triangles that have these corresponding parts are \(\triangle YAZ\) and \(\triangle XAW\).

Answer:

\(\triangle YAZ\cong\triangle XAW\)
