BISECTOR THEOREMS Ms. Branch Integrated Math OBJECTIVES Understands what it means to “bisect” a shape. Bisect a segment. Bisect an angle. MIDPOINT MIDPOINT: The point that bisects a segment –> “Splits into 2 equal parts” A point is “equidistant” from two objects if it’s the same distance from the objects. Image below: D is the midpoint of AB. CD bisects AB. PERPENDICULAR BISECTOR THEOREM If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment. ANGLE BISECTOR An angle bisector is “the line or line segment that divides the angle into two equal parts”, or “a line that splits an angle into two equal angles.” “Bisect” means to divide into two equal parts. ANGLE BISECTOR THEOREM If a point is on the bisector of an angle, then the point is equidistant from the sides of the angle. FOR YOU TO DO 1) Create Flashcards of important key terms from this PowerPoint. 2) Watch videos #1-5 on the Angle & Perpendicular Bisector Blendspace resource. 3) Complete Angle & Perpendicular Bisector Worksheet using compass, straightedge, and protractor. - Turn in Worksheet to folder when complete.
