Perpendicular and Angle Bisectors

Front

What is an angle bisector?

Back

An angle bisector is a ray that divides an angle into two equal parts.

Front

What does a bisector do?

Back

A bisector cuts something in half.

Front

If the measure of angle A is 60 degrees, what is the measure of each angle formed by the angle bisector?

Back

Each angle would measure 30 degrees.

Front

What is the relationship between perpendicular bisectors and segments?

Back

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

What is the definition of a perpendicular bisector?

Back

A perpendicular bisector is a line that is perpendicular to a segment at its midpoint.

Front

If a segment is 20 units long, what is the length of each half when bisected?

Back

Each half would be 10 units long.

Front

What is the significance of the point where the angle bisector intersects the angle?

Back

It is the point that divides the angle into two equal angles.

Front

How do you find the measure of an angle if you know the measures of the two angles formed by the bisector?

Back

Add the measures of the two angles together.
