Diagonals theorem
WebDEFINITION: A trapezoid is a quadrilateral with at least one pair of parallel sides. THEOREM: The median of a trapezoid is parallel to the bases and half the sum of the lengths of the bases. A isosceles trapezoid is a trapezoid with congruent base angles. Note: The definition of an isosceles triangle states that the triangle has two congruent ... WebOne of its diagonals will be right along the horizontal, right like that. Now, this triangle on the top and the triangle on the bottom both share this side, so that side is obviously going to be the same length for both of these triangles.
