✍️Question:-

A quadrilateral in which a pair of a side is parallel is called what?

✍️Answer:-

A quadrilateral in which pair of side is parallel is called a parallelogram.

✍️ What is that?:-

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

✍️It's properties:-

• Opposite sides are congruent (AB = DC).
• Opposite angels are congruent (D = B).
• Consecutive angles are supplementary (A + D = 180°).
• If one angle is right, then all angles are right.
• The diagonals of a parallelogram bisect each other.
• Each diagonal of a parallelogram separates it into two congruent triangles.

✍️Always true properties:-

You'll know that your quadrilateral is a parallelogram if it has these properties of parallelograms:

• The opposite sides are parallel.
• The opposite sides are congruent.
• The opposite angles are congruent.
• Consecutive angles are supplementary (add up to 180-degrees).
• The diagonals bisect each other.
