Angle bisectors. An angle bisector is a line that cuts an angle in half. Example 1: If BD−→− B D → is an angle bisector, find ∠ADB ∠ A D B & ∠ADC ∠ A D C. Since the angle bisector cuts the angle in half, the other half must also measure 55°. ∠ADB =55∘ ∠ A D B = 55 ∘. Add both of these angles together to get the whole angle. Each figure shows a triangle with one of its angle bisectors. 13) Find x if m∠2 = 4x + 5 and m∠1 = 5x − 2. X Y P Z 2 1 14) Find x if m∠2 = 1 + 28 x and m∠XVW = 59 x − 1. V W X P 1 2 15) m∠1 = 7x + 7 and m∠VTU = 16 x + 4. Find m∠1. T U V P 1 2 16) Find m∠2 if m∠2 = 7x + 5 and m∠1 = 9x − 5. C B D P 1 2-2- The angle bisector theorem states that if a point is on an angle bisector, it is an equal distance from the side of the angles. Bisectors can help us learn a great deal of detail about geometric figures that are located within a coordinate plane. This piece of information often helps us form the foundation for geometric proofs.
