9.6 Quadrilaterals

• Grade 4 - Identify Quadrilaterals

2
Set the Purpose

• You have learned to identify parallel lines and
  right angles. Today, you will learn to use these
  features to classify quadrilaterals.
• What is the same about all polygons that are
  quadrilaterals?

3
Quadrilaterals In your notebook, match each
shape with a description! Draw and write the
shape next to each description.

• 1. Opposite sides parallel all sides the same
  length
• 2. Only 1 pair of parallel sides
• 3. 2 pairs of parallel sides
• 4. 4 right angles
• 5. 4 right angles all sides the same length
• Rhombus Trapezoid Parallelogram
  Rectangle Square

4
Quadrilaterals

• A parallelogram has 2 pairs of parallel sides.
• A rectangle has 4 right angles. It is also a
  parallelogram.

5
Quadrilaterals

• A square has 4 right angles and all sides are the
  same length.
• It is a parallelogram, rectangle, and rhombus.

6
Quadrilaterals

• A rhombus is a quadrilateral that has opposite
  sides that are parallel and all of its sides are
  the same length.

7
Quadrilaterals

• A trapezoid is a quadrilateral with only one pair
  of parallel sides.
