4.3 Exploration, example #1
Directions
For #s 1 - 3, do the following:
- Use the polygon tool to trace the pre-image and place a point at the origin.
- Use the rotation tool to rotate the pre-image until the image counter-clockwise so it lines up on the given image.
- Write down the angle of rotation
- State a coordinate rule for the rotation. (Making a table of the pre-image and image coordinates will help greatly in finding the pattern for the transformation)
Example #1
Angle of rotation
The angle of rotation about the origin (in degrees) is:
