## Example 1

**TASK 1 The points of**

**ABC are A(-4,3) B(-3,1) C(-1,2).**

**Rotate the triangle 90**

**clockwise about the origin. Name the new triangle A'B'C' where A corresponds to A', B corresponds to B', and C corresponds to C'.**

**TASK 2
What are the points of the rotated triangle A'B'C'?
**

**TASK 3
What do you notice about the original points and the rotated points?**

## Example 2

**TASK 4 The points of**

**ABC are A(-4,3) B(-3,1) C(-1,2).**

**Rotate the triangle 90**

**counterclockwise about the origin. Name the new triangle A'B'C' where A corresponds to A', B corresponds to B', and C corresponds to C'.**

**TASK 5
What are the points of the rotated triangle A'B'C'?**

**TASK 6
What do you notice about the original points and the rotated points?**

## Example 3

**TASK 7 The points of**

**ABC are A(-4,3) B(-3,1) C(-1,2).**

**Rotate the triangle 180**

**clockwise about the origin. Name the new triangle A'B'C' where A corresponds to A', B corresponds to B', and C corresponds to C'.**

**TASK 8
What are the points of the rotated triangle A'B'C'?**

**TASK 9
What do you notice about the original points and the rotated points?**
