NCERT Solutions for Class 6 Maths Chapter 2 Lines And Angles Ex 2.4

Exercise 2.4

1.

Can you help Rihan and Sheetal find their answers?

Ans:

• It is possible to draw an infinite number of lines through a point in a plane.

• It is possible to draw a single line that crosses two points.

2. Name the line segments in Fig. 2.4. Which of the five marked points are on exactly one of the line segments? Which are on two of the line segments? 

Ans:

Segments of lines: LM, MP, PQ, and QR

Only one line segment contains the points L and R. M, P, and Q are on two segments of a line.

3. Name the rays shown in Fig. 2.5. Is T the starting point of each of these rays?

Ans: 

Ray $\vec{TB}$ and Ray $\vec{TA}$ (also known as Ray $\vec{TN}$). Indeed, T is the origin of both rays:  $\vec{TB}$ and $\vec{TA}$.

4. Draw a rough figure and write labels appropriately to illustrate each of the following:

a. $\overleftrightarrow{OP}$ and $\overleftrightarrow{OQ}$ meet at O.

b. $\overleftrightarrow{XY}$ and $\overleftrightarrow{PQ}$ intersect at point M.

c. Line I contains points E and F but not point D.

d. Point P lies on AB.

Ans:

a. 

b.

c.

d.

5. In Fig. 2.6, name:

a. Five points 

b. A line 

c. Four rays 

d. Five line segments

Ans:

1. Points B, C, D, E and O.

2. Line: DB

3. Rays: $\vec{OB}$, $\vec{OC}$, $\vec{OD}$, $\vec{OE}$.

4. Line segments: DE, EO, OB, DC, DO.

6. Here is a ray $\vec{OA}$ (Fig. 2.7). It starts at O and passes through the point A. It also passes through the point B. 

a. Can you also name it as $\vec{OB}$? Why? 

b. Can we write $\vec{OA}$ as $\vec{AO}$? Why or why not?

Ans:

(a) Since the starting point and direction stay the same, Ray $\vec{OA}$ can alternatively be referred to as Ray $\vec{OB}$

(b) Ray $\vec{OA}$ cannot be designated as ray $\vec{AO}$ since the ray's starting point is O rather than A.
