Front

What is the Perpendicular Bisector Theorem?

Back

If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.

Front

What is a perpendicular bisector?

Back

A line that divides a segment into two equal parts at a 90-degree angle.

Front

If DA is the perpendicular bisector of EI, what can be said about angles IAD and DAE?

Back

Angles IAD and DAE are right angles.

Front

If DA is the perpendicular bisector of EI, what can be said about segments DI and DE?

Back

DI = DE.

Front

What is the measure of segment TP if it is given as 7?

Back

The measure of segment TP is 7.

Front

What does it mean for two segments to be congruent?

Back

Two segments are congruent if they have the same length.

Front

What is the relationship between a point on the perpendicular bisector and the endpoints of the segment?

Back

A point on the perpendicular bisector is equidistant from the endpoints of the segment.

Front

How can you find the midpoint of a segment?

Back

The midpoint can be found by averaging the x-coordinates and the y-coordinates of the endpoints.
