anglebisector
An angle bisector is a ray that divides an angle into two congruent adjacent angles. Imagine an angle formed by two rays originating from a common vertex. An angle bisector is a third ray, also starting from that same vertex, that cuts the original angle exactly in half. If the original angle is denoted as ABC, and BD is the angle bisector, then the angle ABD is congruent to the angle DBC. Consequently, the measure of angle ABD is half the measure of angle ABC.
The concept of an angle bisector is fundamental in geometry. It has numerous applications in constructing shapes,
The construction of an angle bisector can be performed using a compass and straightedge. First, an arc
