Segment and Angle Bisectors

Front

What is a segment bisector?

Back

A segment bisector is a line, ray, or segment that divides another segment into two equal parts at its midpoint.

Front

If line l bisects segment FG, and FG = 34, what are the lengths of FG and EG?

Back

FG = 17, EG = 17.

Front

What is the measure of angles when ray QS bisects angle PQR and m

Back

m

Front

What is the relationship between angles when a ray bisects an angle?

Back

The ray divides the angle into two equal angles.

Front

If angle ABC is bisected by ray BD and m

Back

x = 23.

Front

What is the measure of angles EFJ and JFG if both are equal and m

Back

m

Front

What do you call a point where a line intersects a segment at its midpoint?

Back

It is called the midpoint.

Front

If FG = 34 and EG = 17, is line l a bisector of segment FG?

Back

No, line l is not a bisector because FG is not equal to EG.

Front

What is the definition of a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Front

What is the sum of the measures of angles in a triangle?

Back

The sum of the measures of angles in a triangle is always 180 degrees.
