In the xy-coordinate plane, ΔABC has vertices A(1, -2), B(1, 0.5), and C(2, 1) and ΔDEF has vertices D(4, -3), E(4, 2), and F(6, 3). The triangles are similar because ΔDEF is the image of ΔABC under a dilation. image Which of the following statements is TRUE about the transformation of ΔABC? Select all that apply.

The transitive property of equality states that: o if a = b, then bra o if a = b, then ac = bc o if a = b and b= c, then a = if a = b and c= c, then a + b = b + c

Given: and prove: what is the missing reason in the proof? given transitive property alternate interior angles theorem converse alternate interior angles theorem

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
