HW 6.1 Perpendicular and Angle Bisectors

Front

What is a perpendicular bisector?

Back

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

Front

Define an angle bisector.

Back

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

Front

What is the relationship between the angles formed by an angle bisector?

Back

The angles formed by an angle bisector are congruent.

Front

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

Back

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

Front

What is the measure of each angle in an isosceles triangle if the vertex angle is 40 degrees?

Back

Each base angle measures 70 degrees.

Back

GH represents the length of segment GH in a geometric figure.

Front

What is the significance of the angle bisector theorem?

Back

The angle bisector theorem states that the ratio of the lengths of the two segments created by the angle bisector is equal to the ratio of the lengths of the other two sides of the triangle.
