Which shape is the odd one out? Why?

A
B
C
D

There is more than one answer. D has no right angles. C has sides that are not all equal. B looks different, but it is a square on its corner.

Side
A straight edge of a shape.
Corner
Where two sides meet. Another word for it is vertex.
Right angle
A quarter turn: the corner of folded paper.
Parallel
Going the same way and always the same distance apart.

Put the corner on it. Is it a right angle?

Yes: the same as the corner

Put the corner on it. Is it a right angle?

No: it is bigger
