**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.
