Perpendicular and Angle Bisectors

Front

What is a perpendicular bisector?

Back

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

Front

What is the definition of perpendicular lines?

Back

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

Front

If CD = 12 and EF = 5, what is the length of CF if DF is the perpendicular bisector of CE?

Back

CF = 5.

Front

What is the congruence statement for triangles that are congruent?

Back

If two triangles are congruent, their corresponding sides and angles are equal.

Front

Identify the properties of perpendicular bisectors.

Back

1. Any point on the perpendicular bisector is equidistant from the endpoints of the segment. 2. It divides the segment into two equal lengths.

Front

What is the relationship between angle bisectors and triangle angles?

Back

An angle bisector divides an angle into two equal angles.

Front

How do you find the length of a segment using the perpendicular bisector?

Back

Use the property that any point on the perpendicular bisector is equidistant from the endpoints of the segment.

Front

What is the significance of the point where two perpendicular lines intersect?

Back

The intersection point is the point of right angles, indicating that the lines are perpendicular.

What is the formula for finding the distance between two points in a coordinate plane?

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they never intersect and are always the same distance apart.
