i think this could be helpfule here are the tapizoid rules Trapezoid Picture Example 2 of legs and the Bases base and legs of trapezoid Adjacent Angles of Trapezoid The angles on the same side of a leg are called adjacent angles such as ∠A and ∠D are supplementary. For the same reason, ∠B and ∠C are supplementary. Adjacent Angles of a Trapezoid are supplementary Practice Problem Problem 1 Use the adjacent angles theorem to determine m ∠ZWX Adjacent angles of trapezoidMEASURE OF ANGLE Click for share url http://www.mathwarehouse.com/geometry/quadrilaterals/trapezoid.php#problem1 Problem 2 Use adjacent angles theorem to calculate m ∠MLO Base angles of trapezoidSHOW ANSWER Click for share url http://www.mathwarehouse.com/geometry/quadrilaterals/trapezoid.php#problem2 Problem 3 Find the value of x in the trapezoid below, then determine the measure of angles ∠WXY and ∠XYZ Same Side interior angles of trapezoidSHOW ANSWER Click for share url http://www.mathwarehouse.com/geometry/quadrilaterals/trapezoid.php#problem3 Problem 4 What is wrong with trapezoid LMNO pictured below?
