Question

1. choose the best answer. what part of the protractor does e refer to? diagram of a protractor with labels c, d, e, a, b; numerical markings (e.g., 90, 110, 50, 130, 0, 180) visible options: base line, outer scale, inner scale, origin

Explanation:

A protractor has an inner scale (usually with numbers increasing from left to right in a semicircle) and an outer scale (numbers increasing from right to left). The "E" in the diagram points to the scale that is the inner set of degree markings. The base line is the straight edge (like B), the outer scale would be the other set of numbers, and the origin is the center (like A). So E refers to the inner scale.

Answer:

inner scale
