Task goals
- Rotate a shape by a given angle about a marked centre point using a grid or tracing paper, and identify any invariant points.
- Describe fully a single transformation (naming the type and giving its centre/angle, mirror line, vector, or scale factor including negative values) that maps one given shape onto another.
- Determine and describe fully the single equivalent transformation for a given combination of two or more transformations applied in sequence.
