Identifying a Pair of Congruent Shapes Worksheet Download
The congruent pair is ALWAYS drawn with the second shape turned. That is the whole standard - a rotation preserves congruence - so a pair sitting the same way up would not test it; the turn is what the student has to see past. The three wrong pairs are the three things congruence gets confused with, and each is a real relationship rather than two unrelated shapes: similar (the same shape scaled), the same shape with one measurement changed, and two different shapes that happen to share a side length.

About this worksheet
Four pairs of labelled shapes are shown and students pick the pair that is congruent.
Student objectives
- Recognize that turning a shape does not change its size
- Tell congruent shapes from similar ones
- Compare shapes by every measurement, not just one
- Use side labels to decide whether two shapes match
Everyday practice
- Match a lid to the container that is exactly its size
- Find two puzzle pieces that are the same shape
- Spot matching tiles when picking flooring or wallpaper
- Notice which cookies from a batch are the same size and shape
