## Understanding Elementary Shapes, Exercise 5.7

**Q.1. 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.**

**Ans: ****(a**) True, each angle of a rectangle is a right angle.

(b) True, the opposite sides of a rectangle are equal in length.

(c) True, the diagonals of a square are perpendicular to one another

(d) True, all the sides of a rhombus are of equal length

(e) False, all the sides of a parallelogram are not equal

(f) False, the opposite sides of a trapezium are not parallel

**Q.2. Give reasons for the following:**

**(a) A square can be thought of as a special rectangle.**

**(b) A rectangle can be thought of as a special parallelogram.**

**(c) A square can be thought of as a special rhombus.**

**(d) Squares, rectangles, parallelograms are all quadrilaterals.**

**(e) Square is also a parallelogram.**

**Ans: **(a) Because a square has all the properties as that of rectangle. So, it is a special rectangle.

(b) Because its opposite sides are equal and parallel. So, it is a special parallelogram.

(c) Because its four sides are equal and diagonals are perpendicular to each other. So, it is a special rhombus.

(d) Because they are all enclosed by four sides.

(e) Because its opposite sides are equal and parallel. So, square is also a parallelogram.

** ****Q.3. A figure is said to be regular if its sides are equal in length and angles are equal in measure. Can you identify the regular quadrilateral?**

**Ans: **A square is a regular quadrilateral because all the interior angles are of 90^{0} and all sides are of same length.
