Ddo not necessarily have corresponding parallel sides3 of 54. An altitude is drawn inside an equilateral triangle creating two smaller triangles. Which of the following rigidmotion transformations would prove that the two smaller triangles are congruent?A Reflect one of the smaller triangles about the altitude line.B. Reflect one of the smaller triangles about the base of the equilateral triangle.C. Rotate one of the smaller triangles 180 about the point of intersection of the altitude and the vertex it bisects.D. Rotate one of the smaller triangles 180 about the point of intersection of the altitude and the base of theequilateral triangle.5. Consider the figure to the right.Given: 21 is complementary to 222 is complementary to 23.Prove: 1 a 3Part AComplete the proof.
