# Rotations

## Example 1

TASK 1 The points of ABC are A(-4,3) B(-3,1) C(-1,2). Rotate the triangle 90clockwise 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 90counterclockwise 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 180clockwise 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?
