Lesson Notes:
Lesson 7 is all about transformations, especially dilations and rotations. A rotation is a transformation in which an object turns about a point. Rotations can be either clockwise or counter-clockwise. Rotations can occur on coordinate grids. There are special rotation rules for rotating about the origin. A dilation is a transformation in which an object becomes bigger or smaller. Every dilation has a scale factor. A dilation with a scale factor larger than 1 is an enlargement. A dilation with a scale factor smaller than 1 is a reduction. A dilation also has a center point of dilation.
- Identify and draw dilations.
- Identify and draw rotations.
