Final answer:
Rajesh should choose a diagram that shows two triangles with corresponding pairs of congruent angles and a congruent included side to support his plan to use ASA.
Step-by-step explanation:
Rajesh plans to use ASA to prove that two triangles made from a sheet of paper are the same. ASA stands for Angle-Side-Angle, which is a congruence postulate that states that if two triangles have two corresponding pairs of congruent angles and the included sides are congruent, then the triangles are congruent. To support his plan to use ASA, Rajesh should choose a diagram that shows two triangles with corresponding pairs of congruent angles and a congruent included side.
