Question

# For what values of is ABCD a parallelogram?

Hint:

### Polygon is a two- dimensional closed figure which is consist of three or more-line segments. Each polygon has different properties. One of the polygons is quadrilateral. Quadrilateral is a four-sided polygon with four angles and the sum of all angles of a quadrilateral is . Here, we have to find the value of x in the given quadrilateral using the properties of the quadrilateral.

## The correct answer is:

### In the question there is a quadrilateral PQRS where .

Here, we have to find the value of x for which the given quadrilateral is called as parallelogram.

Since, the opposite angles of a parallelogram are equal.

So, the value of x for which the given quadrilateral is called as parallelogram is .

Therefore, the correct option is a, i.e., .

Parallelogram is a four-sided polygon whose opposite sides are parallel and equal to each other and the opposite angles are equal to each other. The sum of all angles of a parallelogram is and sum of two consecutive angles is . The diagonals of a parallelogram bisect each other and the angle into two equal halves. Here, we have to use these properties of a parallelogram and solve the given question.
