Is a square JUST a
square?

In this lesson you will learn how to name all the “families” a quadrilateral belongs to by looking at multiple attributes.

Let’s ReviewLet’s Review Quadrilaterals with 2 sets of parallel sides:
squarerectangle
parallelogram
rhombus
• 2 sets of parallel sides
• 2 pairs of congruent sides
• 2 sets of parallel sides
• 2 pairs of congruent sides
• 4 right angles
• 2 sets of parallel sides
• 4 congruent sides
• 4 right angles• 2 sets of parallel sides
• 4 congruent sides

Let’s ReviewLet’s Review Quadrilaterals with 1 or less sets of parallel sides:
trapezoid
non-specificquadrilateral
isosceles trapezoid
• 1 set of parallel sides
• 1 set of parallel sides
• 1 pair of congruent sides
• 4 sides

Let’s ReviewA Common Mistake
Thinking that all quadrilaterals are totally separate from each other.
A square and a rectangle are
totally different.Right?
square
rectangleX

Let’s ReviewCore Lesson Compare and contrast a parallelogram and a rhombus.
A parallelogram has:• 2 sets of parallel
sides• 2 pairs of
congruent sides
A rhombus has:• 2 sets of
parallel sides• 4 congruent
sides
parallelogramrhombus
• 2 sets of parallel sides
• 4 congruent sides
• AT LEAST 2 pairs of congruent sides
A rhombus is just a parallelogram with extra attributes, so I say that a rhombus IS a parallelogram.

Let’s ReviewExtension Activities
Draw a picture of all the kinds of quadrilaterals you know. Below your picture, write the most specific name for that quadrilateral and circle it. Below that, write all the OTHER names you can give to that quadrilateral.

Let’s ReviewExtension Activities
Create a graphic representation (example: a shape map) to show how each of the quadrilaterals are connected/related. Be prepared to explain your graphic to another classmate and defend your organization system.
