• # question_answer 30) There are two set-squares in your box. What are the measures of the angles that are formed at their corners? Do they have any angle measure that is common?

We have, two set-squares in our box. In one of them, angles are of ${{30}^{o}},\,{{60}^{o}},\,{{90}^{o}}$and in the others, angles are of ${{45}^{o}},\,{{45}^{o}},\,{{90}^{o}}$. Clearly, they have one angle measure in common, which is ${{90}^{o}}$.
