Only by mathematically proving that the shape has the identifying properties of a parallelogram can you be sure. Theorem 55: The median of any trapezoid has two properties: (1) It is parallel to both bases. In trapezoid ABCD (Figure 3) with bases AB and CD , E the midpoint of AD , and F the midpoint of BC , by Theorem 55: Example 1: In Figure 4, find m ∠ ABC and find BD. The Pythagoreans dealt with the regular solids, but the pyramid, prism, cone and cylinder were not studied until the Platonists. This concept helps in remembering a formula for finding the midpoint of a segment given the coordinates of its endpoints. Example 1: In Figure 1, R is the midpoint between Q(−9, −1) and T(−3, 7). We have discussed all of the theorems involving what a parallelogram is.
