Front

Quadrilateral A, B, C, D is transformed according to the rule (x,y)-- (x, -y) to create quadrilateral A'B'C'D'. Which statement is true?

Back

The angle measures of A'B'C'D' are congruent to the angle measures of ABCD.

Front

Triangle ABC is dilated with the origin as the center of dilation using the rule (x,y) -- (7x, 7y). Which statement is true of triangle A'B'C'?

Back

Triangle A'B'C' is larger than triangle ABC because the scale factor is greater than one.
