**Activity On a sheet of paper, draw a segment and label it segment AB.**

Draw another segment starting at B and ending at C (to make an angle). Fold the paper so that segment AB is on top of segment BC. Use a protractor to measure all the angles involved. What do you notice?

3
Vocabulary Angle Bisector – a segment, ray, line, or plane that intersects an angle into two congruent angles. Bisect – a verb meaning to divide in half (two congruent pieces) A B C D bisects
