Classifying Quadrilaterals

This worksheet is about the properties of quadrilaterals.

You should know the following words:

Bisect              cut a line in half

Parallel            having the same gradient

Right angle      a 90-degree angle

Diagonal          a line inside the shape from one corner to an opposite corner

In quadrilaterals, look out for sides of equal length, parallel sides, diagonals, equal angles etc.

Example

Look at these rhombuses.

All 4 sides are equal

They have 2 pairs of parallel sides

Their diagonals bisect at right angles

They have 2 pairs of equal angles
