Lesson details
Key learning points
- There are clues that can be looked for to determine if a shape has been transformed.
- If the size has changed, one shape may be an enlargement of the other.
- If the orientation has changed, one shape may be a rotation of the other.
- If the shapes are mirrored, one shape may be a reflection of the other.
- If the shapes look identical but are in different places, one may be a translation of the other.
Keywords
Transformation - A transformation is a process that may change the size, orientation or position of a shape.
Congruent - If one shape can fit exactly on top of another using rotation, reflection or translation, then the shapes are congruent.
Invariant - A property of a shape is invariant if that property has not changed after the shape is transformed.
Common misconception
Students may confuse reflections and rotations depending on the object.
A reflection is the only transformation that changes the sense of the object, so check that first.
