Front

What is the Perpendicular Bisector Theorem?

Back

The Perpendicular Bisector Theorem states that if a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.

What is the Angle Bisector Theorem?

Back

The Angle Bisector Theorem states that the angle bisector of an angle divides the opposite side into two segments that are proportional to the lengths of the other two sides.

Solve for x if angle KJL is 28 degrees and angle JKM is supplementary to angle KJL.

Back

x = 180 - 28 = 152 degrees.

If angle A measures 45 degrees, what is the measure of angle B if they are vertical angles?

Back

Angle B also measures 45 degrees because vertical angles are congruent.
