Question

1. choose the best answer. the set of points indicated by 12. is the ____ of the angle. image with points labeled 10, 11, 12, 13? options: vertex, interior, exterior

Explanation:

1. Recall the definitions: The vertex is the common endpoint of the two rays forming the angle. The interior is the region between the two rays, and the exterior is the region outside the angle (not between the two rays).
2. Point 12 is outside the area between the two rays that form the angle. So it belongs to the exterior of the angle. The vertex is a single point (like point 10, maybe the common endpoint), and interior is between the rays. So the correct term is exterior.

Answer:

C. exterior (assuming the options are labeled as A. vertex, B. interior, C. exterior; if the original options have different labels, adjust accordingly, but based on the options given: the correct one is the "exterior" option among the three, so the answer is the option with "exterior".)
