A preimage is graphed. Sides LP and MN are parallel and 4 units apart. How many units apart will they be after they are rotated 90° clockwise?

Question

__units

Answer 1

After a 90° clockwise rotation, the sides LP and MN will still be parallel, but their distance apart will remain the same. Therefore, they will still be 4 units apart.

Answer 2

Luis graphs trapezoid PQRS , in which sides PQ and RS are parallel and 8 inches apart. He then reflects the figure across the y -axis to create trapezoid P′Q′R′S′ . How far apart are the sides P′Q′ and R′S′ ?
The two sides are_____ inches apart.

Answer 3

When a figure is reflected across the y-axis, the x-values of the points are negated while the y-values remain the same. Therefore, the distance between the sides P'Q' and R'S' will be the same as the distance between the original sides PQ and RS, which is 8 inches.

The two sides are 8 inches apart.
