Angle and Perpendicular Bisectors

Front

What is an angle bisector?

Back

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

Front

If AD is the bisector of angle A, what can be said about angle 1 and angle 2?

Back

Angle 1 and angle 2 are equal in measure.

Front

What is the relationship between perpendicular bisectors and triangles?

Back

The perpendicular bisector of a side of a triangle is the locus of points equidistant from the endpoints of that side.

Front

How do you find the length of a segment if given the coordinates of its endpoints?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the measure of angles formed by perpendicular lines?

Back

The measure of angles formed by perpendicular lines is 90 degrees.

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 definition of a perpendicular bisector?

Back

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

Front

How do you determine if two lines are perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

What is the relationship between the angles formed by a transversal intersecting two parallel lines?

Back

The corresponding angles are equal, and the alternate interior angles are equal.

Front

If angle 1 = 23 degrees, what is the measure of angle 2 if AD is the bisector of angle A?

Back

Angle 2 = 23 degrees.
