Question

An angle of $165°$ can not be constructed with a ruler and compasses.

• A. True
• B. False

Answer 1

The correct option is B False

1. As we know that using a ruler and compasses, we can draw angles which are multiples of $15$ only
2. For example-$15,45,75$,
3. As all the above angles are multiples of $15$ so they are constructible
4. As $165$ is also a multiple of $15$
5. Hence, the statement is false.
