how are rays and angles related?
a ray is part of a line that has an endpoint and extends infinitely in one direction, and an angle is two
the measure of an angle related to the length of its sides. so, the measure of an ar vertex.
(options for the angles definition: rays that extend from a common point; rays that extend from a common line segment; lines that intersect at a common point)

Explanation:

An angle is defined as two rays that share a single common endpoint (vertex) and extend infinitely from that point. The length of the rays (sides of the angle) does not affect the angle's measure, as angles are based on the rotation between the two rays, not their length.

Answer:

1. For the blank defining an angle: rays that extend from a common point
2. For the blank about angle measure and side length: not
