Lesson 5 Homework PracticeRotations on the Coordinate Plane

Draw each figure after the rotation described. 1. 270° clockwise rotation about point A 2. 180° clockwise rotation about point A

3. A figure has vertices A(1, 3), B(1, 5), and C(5, 4). Graph the figure and its image after a rotation of 90° clockwise about the origin.

Determine whether each figure has rotational symmetry. If it does, describe the angle of rotation. 4. 5.

6. Many countries have cooperated to build the International Space Station. The flags below represent three of them.

United Kingdom Switzerland Sweden

a. Which flags have rotational symmetry? United Kingdom; Switzerland

b. Describe the angle of rotation for each flag. United Kingdom: 180°; Switzerland: 90°
