**trapezoid**is a quadrilateral**with**one pair**of**opposite**sides parallel**. It**can have**right angles (a right**trapezoid**), and it**can have congruent sides**(isosceles), but those**are**not required.Likewise, how many sides does a trapezoid have and corners?

In 2-dimentional shapes, the point where two sides meet is called a corner, or a vertex. Since trapezoids are quadrilaterals, they have four sides, which means that they also have

**four corners**, or vertices. In order to be considered a trapezoid, a shape must have four sides, and at least one set that is parallel.What are the characteristics of a trapezoid?

Properties of the sides of an isosceles trapezoid: The bases (top and bottom) of an isosceles trapezoid are parallel. Opposite sides of an isosceles trapezoid are the same

**length**(congruent). The angles on either side of the bases are the same size/measure (congruent).
