Either diagonal of a parallelogram divides the parallelogram into two triangles of equal areas. Thus area of triangle abd = half that of the parallelogram abcd. The required ratio is 1 / 2.

To prove that quadrilateral ABCD is a parallelogram, you need to establish one of the following conditions: either both pairs of opposite sides are parallel, both pairs of opposite sides are equal in length, or one pair of opposite sides is both equal and parallel. Alternatively, showing that the diagonals bisect each other or that one pair of opposite angles are equal can also suffice. Any of these conditions will confirm that ABCD is a parallelogram.

A quadrilateral is a parallelogram if one pair of opposite sides are equal and parallel Let ABCD be a quadrilateral in which ABCD and AB=CD, where means parallel to. Construct line AC and create triangles ABC and ADC. Now, in triangles ABC and ADC, AB=CD (given) AC = AC (common side) Angle BAC=Angle ACD (corresponding parts of corresponding triangles or CPCTC) Triangle ABC is congruent to triangle CDA by Side Angle Side Angle BCA =Angle DAC by CPCTC And since these are alternate angles, ADBC. Thus in the quadrilateral ABCD, ABCD and ADBC. We conclude ABCD is a parallelogram. var content_characters_counter = '1032';
