Transformations: Rotated Images
Skill Practice!
Rotate each figure about point R under the given angle of rotation and the given direction. Label the vertices
of the rotation image.
1. 90° counterclockwise 2. 90° clockwise
COORDINATE GEOMETRY
Draw the rotation image of each figure 90° in the given direction about the origin and label the coordinates.
3. △STW with vertices S(2, –1), T(5, 1), and W(3, 3) 4. △DEF with vertices D(-4, 3), E(1, 2), and F(–3, –3)
counterclockwise clockwise
Use a composition of reflections to find the rotation image with respect to lines k and m. Then find the angle
of rotation for each image.
