Answer:

  • D) ASA

----------------------

We are given that:

1) m∠R = m∠C, therefore the two angles are congruent:

  • ∠R ≅ ∠C

2) E is the midpoint of RC, therefore, as midpoint divides the segment in two equal parts:

  • ER ≅ EC

3) As per diagram, TER and VEC are vertical angles, therefore they are congruent:

  • ∠TER ≅ ∠VEC

As we have two angles and included side being congruent, this is Angle Side Angle or ASA congruence.

The matching choice is D.
