Expert Solution
Step 1

Hello. Since your question has multiple sub-parts, we will solve first three sub-parts for you. If you want remaining sub-parts to be solved, then please resubmit the whole question and specify those sub-parts you want us to solve.

(A)

Assume set A be the set of angles in a plane.Let R={(a,b), such that angles a and b are congruent angles}For aA, congruent angles are equal angles.So, (a,a)is a subset for R.Thus, R is reflexive.
