An Associate of Arts is an academic transfer degree designed for students who will ultimately be pursuing a Bachelor of Arts degree at a four-year college/university that is not math or science oriented. Examples of this type of four-year degree are: Business, Liberal Arts, History, Speech, Music, Education, Criminal Justice, etc.
Quadrilaterals which have one pair of parallel sides are called trapezoids. Sides that are parallel are called bases of a trapezoid, and ones that are not parallel are called legs. Trapezoids whose legs are of equal length are called isosceles trapezoids. Diagonals of a isosceles trapezoids are congruent.
The purpose of this task is for students to articulate a definition for a trapezoid. There are two competing definitions for trapezoid: The exclusive definition of a trapezoid states that a trapezoid has exactly one pair of opposite sides parallel. The inclusive definition states that a trapezoid has at least one pair of opposite sides parallel. Sometimes people say trapezoids have one pair of opposite sides parallel, which leaves it ambiguous whether there can be more than one or not.
