12.1.3 Rotations - Worksheet (continued)
Example 3: Rotate the figure with the given vertices about the origin using the given angle of rotation. 7. A (l, 0), B (3, 2), C (5, 0); 90° 8. J (2, 1), K (4, 3), L (2, 4), M ( − 1, 2); 90°
9. D (2, 3), E ( − 1, 2), F (2, 1); 180°
10. P ( − 1, − 1), Q ( − 4, − 2), R (0, − 2); 180°
Example 4: 11. An artist uses a coordinate plane to plan the motion of an animated car. To simulate the car driving around a curve, the artist places the car at the point (10, 0) and then rotates it about the origin by 30°. Give the carʼs final position, rounding the coordinates to the neatest tenth.
