Question

3. The angle which we can’t make using both the Set-squares is _____________

a) 15o

b) 105o

c) 165o

d) 125​

Answer 1

Answer:

15o can be made by keeping 45o and 30o adjacent to each other on the line perpendicular to the line for which 15ois made. Likewise for 105o and 165o also if we just change the alignment with the required line it possible. But to make 125o there is no such combination available for Set-squares.
