UNDERSTANDING QUADRILATERAL

A quadrilateral whose all sides and all angles are equal is:

• Square

• Rhombus

• Trapezium

• parallelogram

A Rhombus is also a:

• Square

• Rectangle

• parallelogram

• None of these

A quadrilateral has 3 acute angles each measuring 70 degree. The measure of 4th angle is:

• 140 degree

• 150 degree

• 105 degree

• 120 degree

If the diagonals of a quadrilateral are equal and bisect each other at 90 degree, then the quadrilateral is:

• Square

• Rhombus

• Rectangle

• parallelogram

The sum of all exterior angles of a regular pentagon is:

• 540 degree

• 360 degree

• 180 degree

• None of these

The sum of all interior angles of a regular hexagon is:

• 720 degree

• 360 degree

• 180 degree

• None of these

The two adjacent angles of a parallelogram are in ratio 2 : 3. measure of these angles are:

• 70 and 110 degree

• 36 and 54 degree

• 72 and 108 degree

• None of these

Each angle of regular hexagon is:

• 140 degree

• 180 degree

• 160 degree

• 120 degree

The number of diagonals a pentagon has:

• 2

• 4

• 5

• 3

A parallelogram having its adjacent sides equal is:

• Trapezium

• Rhombus

• Square

• Rectangle
