Answer 1

The correct option is D protractor

Protractor is an instrument used to measure angles. It has 180 divisions.

To measure with a protractor, the base line of protractor (at $0^{\circ }$) is kept above one of the lines of the angle. The other line then coincides with one of the divisions of the protractor, which gives the measure of the angle.
