Dilation, Translations, Reflections and Rotation

What's the degree of rotation in this image?

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees

This figure is in quadrant 4. If it is rotated 90 degrees counter clockwise, which quadrant will it end in?

• quadrant 1

• quadrant 2

• quadrant 3

• quadrant 4

If this figure is rotated 180 degrees, which quadrant will it end up in?

• quadrant 1

• quadrant 2

• quadrant 3

• quadrant 4

Rotations, like translations and reflections, produce congruent figures.

• true

• false

Plot triangle PQR with points P(-7,-5), Q(-1,-2), R(-1,-5). Rotate the triangle 90 degrees counterclockwise about the origin, then reflect the rotated image over the x-axis. What are the coordinates of the reflection?

• A

• B

• C

• D
