What is a Parallelogram? Mention some properties.
Parallelogram:
If a quadrilateral has a pair of parallel opposite sides, then it is called Parallelogram.
The properties of a parallelogram are as follows:
- The opposite sides are congruent.
- The opposite angles are congruent.
- The consecutive angles are supplementary.
- If anyone of the angles is a right angle, then all the other angles will also be right angles.
- The two diagonals bisect each other.
- Each diagonal bisects the parallelogram into two congruent triangles.
$AB=CD$ and $AD=BC$
$\angle A=\angle C$ and $\angle B=\angle D$
$\angle A+\angle B=180^o$, $\angle A+\angle D=180^o$, $\angle B+\angle C=180^o$ and $\angle C+\angle D=180^o$.
