Question 1.
You have two set squares in your “mathematical instruments box”. Are they symmetric?
Answer:
There are two set squares in the 'mathematical instruments box'.
(i) 30° - 60° - 90° set square - it. is not symmetric.
(ii) 45° - 45° - 90° set square - it is symmetric.

Question 2.
List a few objects you find in your classroom such as the blackboard, the table, the wall, the textbook, etc. Which of them are symmetric and which are not? Can you identify the lines of symmetry for those objects, which are symmetric?
Answer:
Duster, chalk, fan, bulb, tubelight, dustbin etc. are all symmetric objects. Yes, we can identify a line of symmetry for all of them.

Question 1.
How many lines of symmetry does the shape have?

Answer:
This shape has only one line of symmetry.

Question 2.
Do you think that some shapes may have more than one line of symmetry?
Answer:
Yes.

Question 3.
Take a rectangular sheet (like a postcard). Fold it once lengthwise so that one half fits exactly over the other half. Is this fold a line of symmetry? Why?

Answer:
Yes, this fold is a line of symmetry because folding it once along this line, one half fits exactly over the other half.

Question 4.
Open it up now and again fold on its width in the same way. Is this second fold, also a line of symmetry? Why?
Answer:
Yes, the second is also a line of symmetry because on folding it on its width, one half fits exactly over the other half.

Question 5.
Do you find that these two lines are the lines of symmetry?
Answer:
Yes.

Question 1.
Form as many shapes as you can by combining two or more set squares. Draw them on squared paper and note their lines of symmetry.
Answer:
(a) On combining two identical set squares 30°- 60°- 90°, we get the following shapes:

(b) On combining two identical 45°- 45°- 90° set squares, we get the following shapes:

(c) On combining three identical 45°- 45°- 90° set squares.

Question 1.
If you are 100 cm in front of a mirror, where does your image appear to be? If you move towards the mirror, how does your image move?
Answer:
Our image appear to be 100 cm behind the mirror. If we move towards the mirror, then our image also appear to come closer.
