Exploring Quadrilaterals

What is a Quadrilateral? It is a shape with four straight sides. We will try to extend that definition by investigating in greater depth.

Things to Look At Number of Sides Number of Angles Types of Angles Acute Obtuse Right Sum of the Angles

More Things to Look At Consecutive Angles Opposite Angles Consecutive Sides Opposite Sides Diagonals

Interactive Quadrilaterals Quadrilaterals

Our Goal Look at different types of quadrilaterals Identify similarities. Identify differences. Use ruler and/or protractor. Work as a team. Come up with the characteristics of four different quadrilaterals to arrive at a definition for each.

We Will Look at Four Different Types of Quadrilaterals Parallelogram Rectangle Square Rhombus

Parallelogram What can you say about parallelograms?

Rectangle What can you say about rectangles?

Square What can you say about squares?

Rhombus What can you say about the rhombus?
