Which triangle defined by three points on the coordinate plane is congruent with the triangle illustrated? Explain.

A) (5, 4)(7, 4)(5, 0); because corresponding pairs of angles are congruent.
B) (-10, -10)(-6, -10)(-6, -2); because corresponding pairs of angles are congruent.
C) (5, 4)(7, 4)(5, 0); because corresponding pairs of sides and corresponding pairs of angles are congruent.
D) (-10, -10)(-6, -10)(-6, -2); because corresponding pairs of sides and corresponding pairs of angles are congruent.
