How to use this sheet
- Have the child trace the shape on thin paper and slide, flip or turn the tracing to check each answer.
- Move one vertex at a time and label the new points with prime marks, such as A′.
- Ask what stays the same after each transformation: side lengths, angles, size.
Common mistakes
- Reflecting across the wrong axis. A reflection across the x-axis changes the sign of y.
- Rotating the wrong way. Clockwise is the way the hands of a clock move.
- In a dilation, adding the scale factor instead of multiplying by it.
