Quadrilaterals
There are many different types of quadrilaterals. We identify quadrilaterals using their sides and angles.

Let’s Review…
All polygons are made up of line segments and angles. The line segments that create quadrilaterals will be parallel, perpendicular, OR intersecting.
The opposite sides of this quadrilateral are
parallel
.
The adjacent sides of this quadrilateral are
intersecting
.
The adjacent sides of this quadrilateral are
perpendicular
.Slide4
Let’s Review…
The angles that make up polygons will be right angles, acute angles, or obtuse angles.
The angle that makes up this vertex of this quadrilateral is
acute
.
The angle that makes up the vertex of this quadrilateral is
obtuse
.
The angle that makes up this vertex of this quadrilateral is
right
.Slide5
Squares
A square is a quadrilateral that has four equal sides and four right angles.
This square has four right angles and all four sides are congruent (the same length). How many pairs or sets of parallel sides do you see?Slide6
Rectangles
A rectangle is a quadrilateral that has two pairs of parallel sides that are equal and four right angles.
This rectangle has four right angles and two pairs of parallel sides that are congruent. If all four sides were equal, would this shape still be a rectangle?Slide7
Rhombuses
A rhombus is a quadrilateral that has four equal sides and two pairs of parallel sides.
This rhombus has four congruent sides and two pairs of parallel sides. Can a square be a rhombus?Slide8
Trapezoids
A trapezoid is a quadrilateral that has one pair of parallel sides.
This trapezoid has
one pair of parallel sides. Can you identify which two sides are parallel? Do trapezoids have to have sides that are congruent?Slide9
parallelograms
A parallelogram is a quadrilateral that has two pair of parallel sides.
This parallelogram has two pairs of parallel sides. Can you draw a parallelogram that looks different than this one?Slide10
