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 segment EF, joining midpoints E and F of the lateral sides, is called a midline of a trapezoid. A midline of a trapezoid is equal to a half-sum of bases: and parallel to them: EF || AD and EF || BC. A trapezoid with equal lateral sides ( AB = CD ) is called an isoscelestrapezoid. In an isosceles trapezoid angles by each base, are equal ( A = D, B = C ). A parallelogram can be considered as a particular case of trapezoid. Midline of a triangle is a segment, joining midpoints of lateral sides of a triangle.
