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.
All trapezoids have two main parts: bases and legs. The opposite sides of a trapezoid that are parallel to each other are called bases. The remaining sides of the trapezoid, which intersect at some point if extended, are called the legs of the trapezoid. The top and bottom sides of the trapezoid run parallel to each other, so they are the trapezoid's bases. The other sides of the trapezoid will intersect if extended, so they are the trapezoid's legs.
