Which of the following statements are true? A. A dilation is an isometry.
B. A dilation with a scale factor greater than 1 is a reduction.
C. For a dilation, corresponding angles of the image and pre-image are congruent.
D. A dilation image cannot have any points in common with its pre-image.
E. A dilation pre-image must have a point on the center of dilation.
F. A dilation with a scale factor of 4 is an enlargement

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
