What measurements would you take to create a figure congruent to a given: Class 7

Question 1.

What measurements would you take to create a figure congruent to a given : Class 7

(a) Circle

(b) Rectangle

Using this, state how would you check if two —

(a) Circles are congruent?

(b) Rectangles are congruent?

Solution:

(a) Take circles of equal radii.

(b) Take rectangles of equal length and equal breadth.

For checking,

(a) Check whether the two radii are equal.

(b) Check whether the lengths and breadths of the two rectangles are equal.

Question 2.

How would we check if two figures like the one below are congruent? Class 7

Solution:

In both the figures, measure the three line segments and the two angles. After that, we will check whether the corresponding line segments and angles are equal or not.

Use this to identify whether each of the following pairs are congruent. Class 7

Solution:

Yes, both the pairs are congruent.
