In geometry a quadrilateral is a four-sided polygon, having four edges and four corners. The word is derived from the Latin words quadri, a variant of four, and latus, meaning "side".

1. Notes Quadrilaterals
A quadrilateral is a 4-sided polygon. The sum of the measures of the four angles of any
quadrilateral is 360°. Some types of quadrilaterals with which you should be familiar are
shown below.
Type Examples Properties
● Both pairs of opposite
sides are parallel.
● Both pairs of opposite
sides are congruent.
Parallelogram
● Both pairs of opposite
angles are congruent.
● Consecutive angles are
supplementary.
● Both pairs of opposite
sides are parallel.
● Both pairs of opposite
sides are congruent.
Rectangle
● All pairs of adjacent
sides are perpendicular.
● All angles are right
angles.
● Both pairs of opposite
sides are parallel.
● All sides are congruent.
Rhombus ● Both pairs of opposite
angles are congruent.
● Consecutive angles are
supplementary.
● Both pairs of opposite
sides are parallel.
● All sides are congruent.
Square ● All pairs of adjacent
sides are perpendicular.
● All angles are right
angles.
● Exactly one pair of
opposite sides is parallel.
Trapezoid ● Exactly two pairs of
consecutive angles are
supplementary.
