Understanding Angle Bisectors

An angle bisector is a line or ray that divides an angle into two equal angles. This tool simplifies the process of finding the measure of these bisected angles. Simply input the original angle, and the calculator will instantly display the measures of the two resulting equal angles.

Angle bisectors are fundamental in geometry and have various applications, from geometric constructions to more complex mathematical proofs and problems. For instance, in triangles, the angle bisectors intersect at a point called the incenter, which is the center of the triangle's inscribed circle.

Use this calculator to quickly verify your homework, explore geometric properties, or for any situation where you need to bisect an angle!
