Shapes and Angles Chapter 2 Class 5 JKBOSE Solutions
Page No. 16 Solutions
Maryam and Saika are twin sisters. They love doing the same things. One day when they were making shapes with matchsticks.
Anjum gave them a challenge.
Anjum: Maryam will make a shape. Saika has to make the same without looking at it, but she can ask questions.
Saika: Oh! That is so simple.
Maryam made this shape.
Saika: Is it a closed shape or an open shape?
Maryam: It is a closed shape.
Saika: How many sides are there?
Maryam: It has 6 sides.
Saika made this.
Now you give the answers:
Is it a closed shape?
Ans. Yes, it is a closed shape.
Does it have 6 sides?
Ans. Yes, it has 6 sides.
But it is not the same as the one made by Maryam. So Saika tried again.
This is what she made.

Is it a closed shape with 6 sides?
Ans. Yes, it is a closed shape with 6 sides.
Is it the same made by Maryam?
Ans. No, it is not the same as the one made by Maryam.
Is there some way to say in what way these shapes are different?
Ans. Yes, there is a way to say in what way these shapes are different.
Saika is now tired of trying and asks Anjum what to do.
Anjum: If you ask for the angles that the match sticks make at the corners, you can do it.
Saika: Oh! so let us look for the angles.
Look at the angles marked in these shapes.
Can you see the difference?
Ans. Yes, there are different kinds of angles.

Let Us Do These
- Look at the shape and answer.
The angle marked in the black colour is the biggest angle.
- (a) Are the angles marked with yellow equal?
Ans. Yes, the angles marked with yellow are equal.
(b) Are the angles marked with green equal?
Ans. Yes, the angles marked with green are equal.
(c) Are the angles marked with blue equal?
Ans. Yes, the angles marked with blue are equal.
- 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. Yes, we can find other angles which are the same as the one marked in red. The other angles which are the same are marked in the figure.

(b) An angle is formed by ……….. rays.
Ans. An angle is formed by two rays.
(c) The common endpoint is called the ………… of an angle.
Ans. The common endpoint is called the vertex of an angle.
(d) The symbol used for an angle is ……..
Ans. The symbol used for an
(e) Name the given angle.
Ans. The name of the given angle is ∠ABC.
(f) BA and BC are called ……… of the angle.

Changing Shapes
Make 4, 5 and 6-sided shapes by using tube pieces and matchsticks.
Find out how many angles are there easily when pressed. each of these shapes. Mark them.
Ans. There are four angles in figure (a), 5 angles in figure (b) and 6 angles in figure (c). Now push each shape downwards with the tip of your finger.
Does the angles change when pushed down by the finger?
Ans. Yes, the angles change when these figures are pushed downwards with the tip of the finger.

Shapes and Towers
From the activity ‘Changing shapes’ can you guess why triangles are used in these towers, bridges etc?
Ans. Triangles are used in these towers and bridges because their shapes do not change
