Ans 3:

Class : Class 9
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

Ans 4:

Class : Class 8
Both B and C are wrong, so one of the options definitely needs do be changes. Someone please look into this.

Ans 5:

Class : Class 8
both B and C are correct as angle 7.5 can be constructed using compass and ruler and we cant construct a unique triangle with only 3 angles given.

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.
