How it works
Parallel sides never meet. Perpendicular sides meet at a right angle.
Sort shapes by parallel sides and right angles.
A rectangle has two pairs of parallel sides and four right angles.
Worked examples
A rhombus
- A rhombus has 4 equal sides and slanted corners.
- Check its corners: none are square.
- It has no right angle.
A triangle
- A triangle has 3 sides.
- No two sides stay the same distance apart.
- It has no pairs of parallel sides.
A turned rectangle
- A rectangle is turned on its side.
- Turning doesn't change it.
- It still has two pairs of parallel sides.
