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.
