A conjecture and the flowchart proof used to prove the conjecture are shown.
viva [34]

The required proof of parallelogram is given below,

What is parallelogram?

A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry. The opposing or confronting sides and the opposing angles in a parallelogram are of equal length.

For a parallelogram, opposite sides are always equal and parallel.
So for the given parallelogram, we get AD = BC and AD and BC are parallel.

AD and BC is parallel and DC is common side, therefore, \angle 1 = \angle 3 ......(1)

Given \angle 3 = \angle 2  .......(2)

Therefore, from condition (1) and (2), we get

\angle 1 = \angle 2

If \angle 1 = \angle 2 then DC bisects the angle \angle ADE. [Proved]
