2. Mohini tried again and This is what she made.

a. Is it a closed shape with 6 sides?

Ans:  Yes, it is a closed shape with 6 sides

b. Is it the same as the one made by Rohini?

Ans: No, It is different from the shape made by Rohini

c.  Is there some way to say in what way these shapes are different?

Ans: Yes, The shapes of the images are different and the angles are different in the images.

4. Look at the angles marked in these shapes. Can you see the difference?

Ans: Yes, We can see the difference between the images and the angles in the images are different.

Practice Time

1) Look at the shape and answer

a. The angle marked in ________ colour is the biggest angle.

Ans: The angle marked in Black colour is the biggest angle.

2)

(a) Are the angles marked with yellow equal? ________

(b) Are the angles marked with green equal? ________

(c) Are the angles marked with blue equal? ________

Ans:

(a) Are the angles marked with yellow equal? 

Ans: Yes, Angles are equal which is marked with yellow

b) Are the angles marked with green equal?

Ans: yes, Angles are equal which is marked with green

(c) Are the angles marked with blue equal?

Ans: Yes, Angles are equal which is marked with blue

3) Four different angles are marked in four colours. Can you find other angles which are the same as the one marked in red? Mark them in red. Do this for the other colours.

Ans:

4) How many different shapes can you make by changing the angle between the matchsticks in each of these? Try.

Ans:

This is an activity for the students try with altering the matchstick and and the angle then find the number of shapes

Practice Time:

1) Look at the angles in the pictures and fill the table

Ans:

Angle	Right Angle	More than a right angle	Less than a right angle

2) Sukhman made this picture with so many angles.

Ans:

3) Draw anything of your choice around the angle shown. Also, write what kind of angle it is. The first one is done.

Ans:

4) Write 3 names using straight lines and count the angles

Ans:

 5) 

These are two slides in an park.

a) Which slide has a large angle?

Ans: The slide on the right has a larger angle compared to the slide on the left. 

b) Which slide do you think is safer for the little boy? Why?

Ans:The slide on the left is safer for the little boy. This is because it has a smaller angle, making it less steep and thus reducing the speed at which the boy would slide down.A less steep slide generally results in a slower and more controlled descent, which is safer for young children.

6) Find out how many angles are there in each of these shapes mark them.

Ans:

a) In this shape there are 4 angles

b) In this shape there are 5 angles

c) In this shape there are 6 angles

7) Find out and write your results in the table given

Shape	Change in angle yes/no

Ans:

Shape	Change in angle yes/no
	Yes
	Yes
	Yes
	No

Angle and Time:

1) There are many times in a day when the hands of a clock make a right angle. Now you draw some more.

Ans:

2) Write what kind of angle is made by the hands at these times. Also write the time

Ans:

3) Draw the hands of the clock when they make an angle which is less than a right angle. Also write the time.

Ans:

3) Can you guess how many degrees is the angle which is?

(i) 1/2  of a right angle .

Ans: 

Right angle = $90^{\circ}$

Then,$ \dfrac{1}{2}$ of right angle is

$\dfrac{1}{2}\times 90^{\circ}$

=$45^{\circ}$

(ii) ⅓ of a right angle.

Ans:

Right angle = $90^{\circ}$

Then,$ \dfrac{1}{3}$ of right angle is

$\dfrac{1}{3}\times 90^{\circ}$

=$30^{\circ}$

(iii) 2 times of a right angle

Ans:

Right angle = $90^{\circ}$

2 times of a right angle is 

$2\times 90^{\circ}$

$180^{\circ}$
