Quadrilaterals
Quadrilaterals
3.G.1. Understand that shapes in different
categories (e.g., rhombuses, rectangles, and
others) may share attributes (e.g., having four
sides), and that the shared attributes can define a
larger category (e.g., quadrilaterals). Recognize
rhombuses, rectangles, and squares as examples
of quadrilaterals, and draw examples of
quadrilaterals that do not belong to any of these
subcategories.
Quadrilaterals

Quadrilateral means "four
sides" (quad means
four, lateral means side).
A quadrilateral is a four-sided 2
dimensional polygon with four angles.
There are many kinds of
quadrilaterals.
Quadrilaterals
We are going to learn
about the five most
common types.
SQUARE
Square
-All sides congruent
-opposite sides parallel
-four right angles
PARALLELOGRAM
Parallelogram -Opposite sides parallel
-Opposite sides congruent
RHOMBUS
Rhombus-It’s a parallelogram
-four congruent sides
RECTANGLE
Rectangle -Opposite sides parallel
-opposite sides congruent
-four right angles
NOTE:
Squares,
Rectangles and
Rhombuses are all
Parallelograms!
Trapezoid
-Only one pair of sides
is parallel.
