Given: HF || JK; HG ≅ JG Prove: TriangleFHG ≅ TriangleKJG Triangles F H G and K J G connect at point G. Sides F H and J K are parallel. Sides H G and G J are congruent. To prove that the triangles are congruent by ASA, which statement and reason could be used as part of the proof? AngleFGH ≅ AngleKGJ because vertical angles are congruent. AngleJKG ≅ AngleHFG because vertical angles are congruent. AngleFHG ≅ AngleJKG because right angles are congruent. AngleHFG ≅ AngleKJG because alternate interior angles are congruent.
