Write ‘T’ for true and ‘F’ for false of each of the following:

1.	Write ‘T’ for true and ‘F’ for false of each of the following: i. The diagonals of a parallelogram are equal. ii. The diagonals of a rectangle are perpendicular to each other. iii. The diagonals of a rhombus bisect each other at right angles. iv. Every rhombus is a kite.
Answer» i. F The diagonals of square and rectangle only are equal. Rest all the parallelograms like Rhombus etc. do not have diagonals equal in size. ii. F Diagonals of Rectangle do not intersect in right angle hence it is not perpendicular to each other. Only in case of Square, diagonal intersects at right angle. iii. T In rhombus, diagonals bisect the angles and are the perpendicular bisector of each other. iv. F In rhombus, every side has equal length but it in kite only pair of adjacent sides are equal in length.

Answer»

i. F

The diagonals of square and rectangle only are equal. Rest all the parallelograms like Rhombus etc. do not have diagonals equal in size.

ii. F

Diagonals of Rectangle do not intersect in right angle hence it is not perpendicular to each other. Only in case of Square, diagonal intersects at right angle.

iii. T

In rhombus, diagonals bisect the angles and are the perpendicular bisector of each other.

iv. F

In rhombus, every side has equal length but it in kite only pair of adjacent sides are equal in length.
