Transcript Perpendicular and Angle Bisectors

HW: worksheet

Perpendicular Bisector
◦ A segment, line, or ray that is perpendicular to a
segment at its midpoint

Equidistant
◦ Same distance


If a point is on the perpendicular bisector,
then it is equidistant from the endpoints.
If a point is equidistant from the endpoints,
then it is on the perpendicular bisector.

Find AD.
HW: worksheet


If a point is on the bisector of an angle, then
it is equidistant from the sides of the angle
If a point is equidistant from the sides of an
angle, then it lies on the angle bisector

Find the measure of angle GFJ.

The angle bisectors intersect at a point
(called the incenter) that is equidistant from
all sides

In the following diagram, find ND.
