The area of the trapezoid student election sign is 5 square ft find two possible values for each base . Math The Isosceles Trapezoid and its Dissecting Similar Triangles Larry Hoehn Abstract. Isosceles trapezoids are dissected into three similar triangles and re-arranged to form two additional isosceles trapezoids. Moreover, triangle centers, one from each similar triangle, form the vertices of a centric triangle which has special properties. ABDC is a trapezoid in which AB and CD are parallel sides measuring 6 and 9, respectively. Angles ABC and BCD are both right angles.
