Question

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

Explanation:

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

• "origin" is the center point (like \( A \)), not \( D \).
• "outer scale" is the scale on the outer edge of the protractor. Looking at the diagram, \( D \) is on the outer - most set of degree markings (the outer scale), which has numbers like 90, 110, etc.
• "degree markings" is too general; we need to be more specific about the scale.
• "inner scale" is the inner set of markings (like the one with 50, 130, etc.), which is not \( D \).

Answer:

outer scale
