Say True or False :
(a) Each angle of a rectangle is a right angle.
(b) The opposite sides of a rectangle are equal in length.
(c) The diagonals of a square are perpendicular to one another.
(d) All the sides of a rhombus are of equal length.
(e) All the sides of a parallelogram are of equal length.
(f) The opposite sides of a trapezium are parallel.

To do:

We have to find whether the given statements are true or false.

Solution:

(a) We know that each angle of a rectangle is a right angle.

Therefore, the given statement is true.

(b) We know that the opposite sides of a rectangle are equal in length.

Therefore, the given statement is true.

(c) We know that the diagonals of a square are perpendicular to one another.

Therefore, the given statement is true.

(d) We know that all the sides of a rhombus are equal in length.

Therefore, the given statement is true.

(e) We know that opposite sides of a parallelogram are equal.

Therefore, the given statement is false.

(f) We know that in a trapezium exactly one pair of opposite sides are parallel to each other.

Therefore, the given statement is false.
