Question

1. choose the best answer. what part of the protractor does c refer to? image of a protractor with labels c, d, e, a, b and degree markings options: base line, inner scale, degree markings, outer scale

Explanation:

To determine what part of the protractor \( C \) refers to, we analyze the options:

• "base line" is the straight edge (like \( B \)), so not \( C \).
• "inner scale" is the inner set of numbers (e.g., 130, 50), not \( C \).
• "degree markings" are the small ticks, but \( C \) is a scale.
• "outer scale" is the outer set of numbers (e.g., 50, 90, 110), and \( C \) points to the outer numbers (50), so it's the outer scale.

Answer:

outer scale
