An altitude is drawn inside an equilateral triangle creating two smaller triangles. Which of the following rigid 5 Part B motion transformations would prove that the two smaller triangles are congruent? The proof in Part A establishes which of the following theorems? A. Reflect one of the smaller triangles about the altitude line. A. Angles that are complementary to each other are congruent. B. Reflect one of the smaller triangles about the base of the equilateral triangle. B. Angles that are complementary to the same angle are congruent C. Rotate one of the smaller triangles 180 about the point of intersection of the altitude and the vertex i bisects. C. Angles that are complementary to adjacent angles are congruent D. Rotate one of the smaller triangles 180 about the point of intersection of the altitude and the base of the D. Angles that are complementary to congruent angles are congruent. equilateral triangle. 6. In the diagram, Im || n and t is a transversal through m and a. Consider the figure to the right. Part A m Provi 23 2 26 Given: 21 is complementary to z2 Select the appropriate statements and reasons from the list and /2 is complementary to 23. enter them into the empty bakes to correctly complete the proof. Prove: 21 m 23 A 22 - 23 Part A Complete the proof. Write the appropriate options from the list to correctly complete the proof. D When parallel lines are cut by a transversal, alternate exterior angles are congruent mci+m/2 F definition of angle measurements definition of complementary E When parallel lines are cut by a transversal, comesponding angles are congruent angles C m/2 +m/3 When two angles are congruent to the same angle, the two mighas complimentary angles are are congruent to each other. definition of congruent angles congruent When parallel lines are cut by a transversal, afternate Interior angles subtraction property of equality are congruent 1. 21 Is complementary to 22 and 2 2 Is complementary to 23 because this is given Information. 2. my1 + mc2 - 90' and m/ 2 + m.
