Geometry and Measurement: Transformations, Level 3
AO1: Describe the transformations (refl ection, rotation, translation, or enlargement) that have mapped one object onto another. This means students will explore describe transformations. “Transformation” is a generic term used to describe actions on shapes that result in some form of pattern, usually symmetric. A reflection is the image of a shape as seen through a mirror line either inside or outside the shape, sometimes called a “flip”. A rotation is the image of the shape turned about a point either inside or outside the shape. A translation is the image of a shift of the shape along a line, and an enlargement is the image of the shape made bigger or smaller by some scale factor. At Level Three students should be able to compare the image of a shape with the original and describe the transformation. This can include a sequence of two transformations. For example:
|
|
|
|
|
A' is the image of A |
B' is the image of B |
C' is the image of C |
