Which tool is used to measure angles accurately?

Explanation:
The tool used to measure angles accurately is the protractor. A protractor has degree markings and a baseline, so you align the vertex of the angle with the center point and read the angle where the sides cross the scale. This directly gives you the angle in degrees, which is essential for checking slopes, alignments, or components in escalator/mechanical installations. The other items don’t measure angles: a tread is the horizontal stepping surface, a straight edge is used for drawing or checking straightness rather than reading an angle, and a riser is the vertical portion between steps.
