If ABCD is a parallelogram, what is the value of x?35
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, we can use the properties of the angles and the bisected segment. Since angle 1 is congruent to angle 2 and BD bisects segment AC at point A, it follows that triangle ABD is congruent to triangle CDB by the Angle-Side-Angle (ASA) criterion. This congruence implies that sides AB and CD are equal and sides AD and BC are equal, which are the defining properties of a parallelogram. Therefore, quadrilateral ABCD must be a parallelogram.
