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 an angle bisector?

Back

An angle bisector is a line that divides an angle into two equal angles.

Front

If RT bisects SU, what can be said about RU and SV?

Back

RU and SV are equal in length.

Front

How do you find the length of a segment when given a bisector?

Back

If a segment is bisected, divide the total length by 2 to find the length of each half.

Front

What does it mean if there is 'not enough information' to find a length or angle?

Back

It means that the given data does not provide sufficient details to calculate the unknown value.

Front

If RU = 8, what is the length of SU when RT bisects SU?

Back

SU = RU + SV = 8 + 5 = 13.

Front

What is the relationship between angles formed by perpendicular lines?

Back

Perpendicular lines form four right angles (each measuring 90 degrees).

Front

How can you determine if two angles are congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the sum of the angles in a triangle?

Back

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

Front

If angle ADB is not enough information to find its measure, what does that imply?

Back

It implies that additional information or measurements are needed to determine the angle's measure.
