A ray is drawn to divide an angle into two equal angles. This process is called ____

The process of drawing a ray to divide an angle into two equal angles is called "angle bisector." An angle bisector is significant in both geometric constructions and various applications in solving problems related to triangles, quadrilaterals, and other polygons.

When a ray bisects an angle, it creates two angles that are congruent, meaning they have the same measure. This is often utilized in various fields such as engineering, architecture, and design to ensure precision. The angle bisector has properties that can be applied to find distances and relationships between various elements in geometric figures. Understanding angle bisectors can also aid in proving theorems and solving geometrical problems more effectively.

In summary, the term you are looking for is "angle bisector."
