Which of the following describes the image of a triangle after a dilation that has a scale factor of 5/6? 1. Each angle has the same measure as its corresponding angle in the pre-image

2. Each side has the same measure as its corresponding angle in the pre-image.

3.Each angle has 5/6 of the measure of its corresponding angle in the pre-image

4. Each side has 6/5 the length of its corresponding length in the pre-image.

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.
