Question
Construct the following angles using set-squares: $75^\circ $
✓
Answer
Place $45^\circ $ set-square and make an angle of $45^\circ $ by drawing the rays $BD$ and $BC$ as shown in the figure.
Now place the vertex of $30^\circ $ of the set- square on the ray $BD$ as shown in the figure and draw the ray $BA$. The angle so formed is $75^\circ $. Therefore, $\angle\text{ABC}=75^{\circ}$
(Line $BD$ is hidden)
