Trapezoids
The trapezoid or trapezium is a quadrilateral with two parallel sides.
Types of Trapezoids
Right Trapezoid
A right trapezoid has two right angles.
Isosceles Trapezoid
An isosceles trapezoid has two of its non-parallel sides equal in length.
Scalene Trapezoid
A scalene trapezoid doesn´t have equal sides or angles.
Area of a Trapezoid
The area of the trapezoid is equal to the sum of its bases multiplied by its height, divided by two.
Oblique Side of a Right Trapezoid
Isosceles Trapezoid Height
Examples
