Which triangle defined by three points on the coordinate plane is congruent with the triangle illustrated, and why? a) (0, -4)(6, 6)(6, -4); because corresponding pairs of angles are congruent. b) (0, -2)(3, 3)(3, -2); because corresponding pairs of angles are congruent. c) (0, -4)(6, 6)(6, -4); because corresponding pairs of sides and corresponding pairs of angles are congruent. d) (0, -2)(3, 3)(3, -2); because corresponding pairs of sides and corresponding pairs of angles are congruent.
