Look at the picture to the left showing Triangle ABC and Triangle A’B’C’.
_____________________
Think about what transformation(s) are needed to map one triangle to the other.
Trace Triangle ABC on your transparent copy paper.
Can you map one triangle to the other using one or more translations?
Can you map one triangle to the other using one or more reflections?
Can you map one triangle to the other using a rotation around the origin?

2. PROMPTS: Begin with (0, 1) as your point of rotation.

PROMPTS:
Begin with (0, 1) as your point of rotation.
The images appear to show a rotation of 180 degrees. When using the origin as the point of rotation, what did you notice?
_____________________
We are going to experiment with Triangle ABC. The point of rotation is going to be modified from (0,0) to another point.
_____________________
RULES: Use the points below as your new point for rotation.
(0, 1) (1,0) (-1,0) and (0,-1)
Describe how changing to point of rotation works.
Will a single 180 degree rotation map it together?
