Question

1. choose the best answer. the set of points indicated by 11. is the _____ of the angle. image with labeled points 10, 11, 12 options: interior, exterior, vertex

Explanation:

To determine the correct term, we recall the definitions:

• The vertex of an angle is the common endpoint of the two rays forming the angle.
• The interior of an angle is the set of points between the two sides (rays) of the angle.
• The exterior is the set of points outside the angle.

From the diagram (interpreted as an angle with a vertex and two rays), the set of points labeled 11 lies between the two sides of the angle, so it is the interior. The "vertex" is a single point (not a set of points), and "exterior" would be outside the angle.

Answer:

A. interior
