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?
