Question: 1 / 400

What is the geometric figure formed by two rays sharing a common endpoint called?

Line segment

Angle

The geometric figure formed by two rays that share a common endpoint is known as an angle. In geometry, an angle is defined by the two rays, which are called the sides of the angle, and the point where they meet is known as the vertex.

When two rays extend from the same endpoint, they create a space between them that quantifies the angle measure—often measured in degrees. The concept of an angle is fundamental in various branches of mathematics and helps understand relationships and shapes in geometric figures.

Other choices describe different geometric concepts. A line segment refers to the part of a line that is bounded by two distinct endpoints, while a point represents an exact location in space with no size or dimensions. A plane is a flat, two-dimensional surface that extends infinitely in all directions. Hence, the description provided fits perfectly with the definition of an angle.
