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

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 adjacent sides of this quadrilateral are perpendicular. The adjacent sides of this quadrilateral are intersecting. The opposite sides of this quadrilateral are parallel.

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.

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?

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?

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?

A trapezoid is a quadrilateral that has one pair of parallel sides. 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?

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?

Quadrilaterals With your newly found knowledge, you will be able to identify quadrilaterals everywhere! Try it out on these!
