## NCERT Solutions for Class 6 Maths Chapter 4 Basic Geometrical Ideas Ex 4.2

Ex 4.2 Class 6 Maths Question 1.

Classify the following curves as

**(i)** Open or

**(ii)** Closed.

Solution:

Open curves are (a) and (c) and closed curves are (b), (d) and (e).

Ex 4.2 Class 6 Maths Question 2.

Draw rough diagrams to illustrate the following:

**(a)** Open curve

**(b)** Closed curve

Solution:

Rough diagram to illustrate

**(a) Open curve is**

**(b) Closed curve is**

Ex 4.2 Class 6 Maths Question 3.

Draw any polygon and shade its interior.

Solution:

We know that in a closed curve, the interior is inside of the curve. Thus, shaded portion of the polygon indicate its interior.

Ex 4.2 Class 6 Maths Question 4.

Consider the given figure and answer the questions:

**
(a)** Is it a curve?

**(b)**Is it closed?

Solution:

**(a)**Yes, the given figure represents a curve.

**(b)**Yes, the curve is closed.

Ex 4.2 Class 6 Maths Question 5.

Illustrate, if possible, each one of the following with a rough diagram:

**(a)** A closed curve that is not a polygon.

**(b)** An open curve made up entirely of line segments.

**(c)** A polygon with two sides.

Solution:

**(a)** Impossible, as a close plane figure bounded by lines is called a polygon.

**(b)** Yes, it may be as

**
(c)** No, impossible, as a polygon of two sides cannot be drawn.
