Aditya that is the very reason why it will be a unique triangle and option C is correct since it an angle such as that can be created by bisecting 60 degree three times

Class : Class 8

## Ans 4:

Class : Class 8
ans is b.i agree with aditya

Class : Class 8

## Ans 6:

Class : Class 5
The option b states that a unique triangle is constructed and it is possible to do so. However option c states that we CANNOT construct the angle 7.5. This is false cause it can be constructed by bisecting an angle of 60, three times.
