Unit 8, Lesson 10-- Investigating Quadrilaterals

Lesson 10-- Investigating Quadrilaterals

Introduction

Hello Mathematicians! Today we will investigate quadrilaterals.

Visual

Take a look at these special types of quadrilaterals.  What do you notice about their angles, lines, and side lengths?

Directions:

  • Today, you will sort shapes by their similarities and differences.
  • Look for:
    • right angles
    • sets of parallel lines
    • sets of sides with equal length
  • Use the drawing tools to draw circles around groups of shapes and label the groups (for example:  "all sides equal" or "all right angles").  Some shapes may overlap groups. You may also leave shapes outside of the rings you create.
  • What would be a label for the entire group?
