A figure that is made up of two noncollinear rays with a common endpoint is an angle. The angle that is formed can be acute, right, obtuse or reflex.

The term defined as two noncollinear rays that share a common endpoint is "angle." In geometry, an angle is formed by two rays that originate from a common point, known as the vertex, and extend in different directions, not lying on the same line.
A noncollinear ray is a ray that is not a straight line. So even two of these could criss-cross infinitely many times. It is impossible, therefore, to answer the question.
Noncollinear rays are those that do not lie on the same line, meaning they point in different directions and cannot be extended to intersect at a single point. Noncoplanar rays, on the other hand, are rays that do not lie within the same plane, indicating that they exist in different three-dimensional orientations. Therefore, while both terms refer to geometric relationships, noncollinear rays pertain specifically to lines, while noncoplanar rays pertain to planes.

An angle is the figure formed by two rays sharing a common endpoint, called the vertex of the angle.
Ten.Each angle is determined by two rays, so the answer is equivalent to the number of combinations of 2 out of 5 = 5*4/(2*1) = 10
