Katherine wants to prove that the measures of the interior angles of a triangle have a sum of 180°. She draws a triangle and extends one of the sides through a vertex. She then draws a line through this vertex that is parallel to the opposite side, as shown in the diagram below. 3 Which of the following statements must be true and could be used as part of Katherine's proof? Select all that apply. c. mz3 = mz4 + m25 b. mz2 = mz4 e. mz1 + m-2 + mz4 + m²5 = 180° d. mz3 + mz4 + mz5 = 180° a. mz1 = m25
