Question

select the correct answer from each drop - down menu.
how are rays and angles related?
a ray \boxed{} part of a line that has an endpoint and extends infinitely in one direction \boxed{}, and an angle is two rays that extend from a common point \boxed{}. the measure of an angle \boxed{} related to the length of its sides. so, the measure of an angle \boxed{} the same at all distances from its vertex.

Explanation:

1. First drop - down: A ray is defined as part of a line that has an endpoint and extends infinitely in one direction. This is the standard definition of a ray.
2. Second drop - down: An angle is formed by two rays that extend from a common point (the vertex of the angle). This is the basic definition of an angle, where the two rays are the sides of the angle.
3. Third drop - down: The measure of an angle is not related to the length of its sides. The measure of an angle depends on the amount of rotation between the two rays (sides) of the angle, not on how long the rays are.

Answer:

First drop - down: is
Second drop - down: two
Third drop - down: is not
