Question

# The length of side AB is _____.

- 4 cm
- 6 cm
- 10 cm
- 2 cm

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 measure of AB in the given quadrilateral using the properties of the quadrilateral.

## The correct answer is: 6 cm

### In the question there is a figure consist of two parallelograms ABCD and CDEF as shown in the figure.

Here, we have to find the length of the AB.

Since, the opposites of a parallelogram are equal.

So, in parallelogram CDEF, CD=EF= 6 cm.

Similarly, in parallelogram ABCD, AB=CD= 6 cm.

Thus, the length of AB is 6 cm.

Therefore, the correct option is b, i.e., 6 cm.

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.
