Question

what method can be used to prove the triangles below are congruent: sas aas asa not possible

Explanation:

Step1: Analyze congruence criteria

SAS (Side - Angle - Side) means two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle. AAS (Angle - Angle - Side) is two angles and a non - included side. ASA (Angle - Side - Angle) is two angles and the included side.

Step2: Observe the triangles

From the arrows on the sides of the triangles in the figure, we can assume two sides are congruent. And the vertical angles (the angles formed by the intersection of the common side) are congruent. This gives us two sides and the included angle congruent, which is SAS.

Answer:

A. SAS
