Question

An angle opens towards the right. After placing the vertex correctly, you align the bottom arm with the baseline. Which scale will you most likely use?

पर्याय

• Both scales, then find the average.

• The outer scale (starting from the left).

• Neither scale; the angle cannot be measured.

• The inner scale (starting from the right).

Answer 1

The inner scale (starting from the right).

Explanation:

On a standard protractor, the inner scale has its 0° mark on the right, which is used for angles opening in that direction.
