3. The angle which we can’t make using a single Set-square is ________

a) 45^{o}

b) 60^{o}

c) 30^{o}

d) 75^{o}

### View Answer

^{o}can be drawn using 45

^{o}Set-square, and 30

^{o}, 60

^{o}can be drawn using 30

^{o}– 60

^{o}Set-square, but to draw 75

^{o}degrees we need both Set-squares. That is only if we keep 30

^{o}of set-square adjacent with 45

^{o}set-square we can get 75

^{o}. And also multiple angles can be achieved using protractor.

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

a) 15^{o}

b) 105^{o}

c) 165^{o}

d) 125^{o}

### View Answer

^{o}can be made by keeping 45

^{o}and 30

^{o}adjacent to each other on the line perpendicular to the line for which 15

^{o}is made. Likewise for 105

^{o}and 165

^{o}also if we just change the alignment with the required line it possible. But to make 125

^{o}there is no such combination available for Set-squares.
