Benefits of Angle Bisectors Worksheets. In geometry, the angles are classified as acute, right, obtuse and straight, angle bisectors worksheets will help the students learn about these different types of angles. worksheets give students the opportunity to solve a wide variety of problems helping them to build a robust mathematical foundation.
These worksheets will require a protractor. You need to measure the angles and find and draw the exact spot where a bisector would be placed. Students often have fun with these types of worksheets. These worksheets explain how to bisect an angle. Students will need to use a compass and straightedge for most of the problems.
An angle bisector is a ray that divides an angle into two angles that are congruent. In the photograph of the hang glider, BD&*( bisects aABC because it divides the angle into two congruent angles. If BD&*( bisects aABC, then the measures of aABD and aDBC are half the measure of aABC. Also, the measure of aABC is twice the measure of aABD or aDBC .

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.
