If you were to rotate ABCD 90° counterclockwise about the origin, what would the coordinate of A' be?

• (-5, 5)

A transformation is applied to a figure to create a new figure on a coordinate grid. Which transformation does NOT preserve congruence?

• A dilation by a scale factor of 1.5

• A reflection across the y-axis, or x-axis

• A translation of 125 units down

Answer explanation

Clue:

Translations, Reflections, Rotations = Preserve Congruency.

Dilation = Does not preserve Congruency.
