# Let’s write what conditions are required to draw a fixed parallelogram.

Answer :

We are supposed to write the conditions required to draw a fixed parallelogram, that is, a quadrilateral.

Let us understand what a condition is.

Condition is a requirement necessary for a given statement or theorem to hold. Also called a criterion.

Let us fix the base at the length of 6 cm.

The conditions required to draw a fixed parallelogram are:

1. Sides are equal and parallel: There are four sides in a parallelogram, and the opposite sides are equal and parallel. So, once the base is fixed at length 6 cm, the opposite side also measures 6 cm. Also, these two sides are parallel.

While take the other opposite sides to be of same length, say, of 5 cm and parallel to each other.

2. Opposite angles are equal: There are four angles in a parallelogram. Check for opposite angles to be equal.

A fixed parallelogram can be formed using these two simple conditions.
