Part 1 out of 3

a square on the coordinate plane has vertices at

(−3, 3), (3, 3), (3, −3),
and (−3, −3).

a dilation of the square has vertices at
(−9, 9), (9, 9), (9, −9),
and (−9, −9).

find the scale factor and the perimeter of each square.

me out asap i don't understand how to find the scale factor ; -;

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
