QUADRILATERALS

Two sides of a parallelogram are in the ratio 3 : 1. If its perimeter is 56 cm, find the lengths of its sides.

• 35 cm , 21 cm

• 21 cm , 7 cm

• 16 cm , 12 cm

• 14 cm, 7 cm

Name the following parallelogram :

The diagonals are unequal and the adjacent sides are equal.

• Parallelogram

• Rhombus

• Kite

• Rectangle

The diagonals of a rectangle are perpendicular to each other.

• True

• False

The diagonals of a rhombus are equal.

• True

• False

A figure is said to be regular if

• its sides are equal in length and angles are complementary.

• its sides are parallel and angles are equal in measure.

• its sides are equal in length and angles are equal in measure.

• its sides are equal in length and angles are supplementary.

The sum of all the angles of a quadrilateral is

• $90^o$

• $180^o$

• $360^o$

• $270^o$
