opposite sides AB and DC are parallel and congruent, and . Rhombus: A closed four-sided figure with parallel opposite sides. Lines AB and DC are the non-parallel sides and are called legs. Also, the opposite sides are equal in length. The Sum of adjacent angles of a parallelogram is equal to 180 degrees. 3. 50º and 130º are supplementary. There are six important properties of parallelograms to know: Opposite sides are congruent (AB = DC). All the four sides are of equal lengths. In a triangle, a median is a line joining a vertex with the mid-point of the opposite side. Alternate angles (alt.\(\angle\)s) lie on opposite sides of the transversal, but are not adjacent or vertically opposite. Vectors Medians of a triangle, G point, formulas for calculating length . Lines AC (or q) and BD (or p) are called diagonals The line perpendicular to lines AD & BC is called the height or altitude. A parallelogram has no lines of symmetry.
