Perpendicular and Angle Bisectors

Front

What does a bisector do?

Back

A bisector cuts something in half.

Front

What is an angle bisector?

Back

An angle bisector cuts an angle into 2 equal pieces.

Front

Solve for the value of x: 2x + 5 = 25.

Back

x = 10.

Front

What ray is the bisector of \( \angle AOC \)?

Back

The ray \( \overrightarrow{OB} \) is the bisector of \( \angle AOC \).

Front

What is the measure of the segment \( \overline{EG} \) if it is given as 10?

Back

The measure of \( \overline{EG} \) is 10.

Front

Define perpendicular lines.

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

What is the relationship between perpendicular bisectors and segments?

Back

A perpendicular bisector divides a segment into two equal parts at a right angle.

Front

How do you find the angle bisector of an angle?

Back

To find the angle bisector, draw a ray from the vertex that divides the angle into two equal angles.

Front

What is the measure of a right angle?

Back

The measure of a right angle is 90 degrees.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of the measures of complementary angles is 90 degrees.
