Classifying Quadrilaterals
More Quadrilaterals
Students should be able to:
- classify and describe quadrilaterals by using their properties; e.g. perpendicular/parallel sides, congruent angles/sides.
What is a quadrilateral?
A quadrilateral is a four-sided shape with four angles.

All of the angles inside a quadrilateral add up to 360 degrees. Some quadrilaterals have angles that are all congruent, or equal in size (squares and rectangles); others have opposite angles congruent (parallelograms); and still others have no congruent angles. To classify quadrilaterals properly, you must be able to see what kind of angles are inside them.

Finding Parallel Sides
Quadrilaterals have four sides that intersect at four vertices. On some quadrilaterals the sides opposite each other are parallel to each other. To classify quadrilaterals properly, you must be able to see which ones have sides that are parallel to each other.

Congruent Sides
Quadrilaterals have four sides. On some quadrilaterals all four sides are congruent, or the same length. Other quadrilaterals have opposite sides congruent while still others have no side congruent.
