When we talk about what the angle bisector is, then it is any point, segment, ray, or line that cuts an angle into two equal congruent angles, called an angle bisector. For example if the two parallel lines are x = 1 and x = − 1 then the "middle" line will be x = 0. Depending on the inclination between the two arms, an angle may be acute (less than 90-degrees, like 60-degree angle), obtuse (more than 90-degrees) or right angle (exactly 90-degrees). In a triangle, an angle bisector is a line which bisects an angle of the triangle.
