Front

What does it mean for a point to be a midpoint?

Back

A midpoint is a point that divides a segment into two equal lengths.

Front

If RM = 6, what is the length of MS if M is the midpoint?

Back

MS = 6, since RM and MS are equal.

Front

If RM = 3, what is the length of MS if M is the midpoint?

Back

MS = 3, since RM and MS are equal.

Front

What is the relationship between a bisector and congruence?

Back

A bisector creates two congruent segments or angles.

Front

In a triangle, what does the angle bisector do?

Back

An angle bisector divides the angle into two equal angles.

Front

What is the significance of the perpendicular bisector?

Back

A perpendicular bisector is a line that is perpendicular to a segment at its midpoint, creating two right angles.

Front

How do you find the length of a segment if you know the lengths of the two congruent segments created by a bisector?

Back

Add the lengths of the two segments together.

Front

If a line bisects an angle of 60 degrees, what are the measures of the two angles created?

Back

Each angle measures 30 degrees.

Front

What is the definition of congruent segments?

Back

Congruent segments are segments that have the same length.
