What do we call any shape with 4

sides?

A quadrilateralA quadrilateral

•“quad” means 4•“lateral” means side

Does a quadrilateral have more sides or more angles?

Does a quadrilateral have more sides or

more angles?

A quadrilateral has 4 sides and 4 angles!

What kind of angles does a square have?

Right Angles, 4 of them

Are these lines parallel?

Yes! Remember, parallel lines are lines in a plane that are always the

same distance apart.

Example:

Gymnasts use parallel bars

How many pairs of parallel lines in this regular hexagon?

3 pairs of parallel lines 1 2 3

3 2 1

How many parallel lines on a triangle?

There are no parallel lines on a triangle!

Work with your group:Use the rulers and the geo-dot paper on your desks to

draw as many different quadrilaterals as you can in

5 minutes. Label and cut your quadrilaterals out.

QUADRILATERALS DEFINED

Quadrilateral A polygon with four sides and four angles

kite A quadrilateral with exactly two pairs of congruent sides that are next to each other; no two sides are parallel

A Closer Look at Quadrilaterals: ParallelogramsUse what you have learned today about parallelograms to

label and describe each shape. Include the reasons why the arrows are drawn as they are.

                   

On the back: Draw and label at least one quadrilateralthat is not on this chart, and tell why it was not included here.
