Perpendicular and Angle Bisectors

Lines that intersect at a right angle (90 degrees).

A line that divides a segment into two equal parts at a right angle.

A ray that divides an angle into two congruent angles.

The measure of the angle is divided equally by the angle bisector.

Perpendicular lines create four right angles at the point of intersection.

The sum of the angles formed is 360 degrees.

The point that divides the segment into two equal lengths.

Two lines are perpendicular if the product of their slopes is -1.

Angles that share a common side and vertex but do not overlap.

Angles that are across from each other when two lines intersect.
