Question

select the correct answer
which statement best defines an angle?
a. two rays that share a common endpoint called the vertex
b. two line segments that intersect at a point called the vertex
c. two lines that intersect at a point called the vertex
d. two lines that share a common line segment called the vertex

Explanation:

An angle is formed by two rays that start from the same common endpoint, which is defined as the vertex. Line segments intersecting or two lines intersecting do not match the standard definition of an angle, and the description in option D is geometrically incorrect.

Answer:

A. two rays that share a common endpoint called the vertex
