Segment and Angle Addition Review

Front

What is the Segment Addition Postulate?

Back

The Segment Addition Postulate states that if point B is between points A and C, then AB + BC = AC.

Front

What is the Angle Addition Postulate?

Back

The Angle Addition Postulate states that if point B is in the interior of angle AOC, then m∠AOB + m∠BOC = m∠AOC.

How do you find the length of a segment given two endpoints?

Back

To find the length of a segment given two endpoints A(x1, y1) and B(x2, y2), use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

What is the formula for finding the measure of an angle formed by two intersecting lines?

Back

The measure of an angle formed by two intersecting lines can be found using the property that vertical angles are equal.

Front

What does it mean for angles to be complementary?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What does it mean for angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

How do you solve for x in an equation involving angles?

Back

To solve for x in an equation involving angles, isolate x on one side of the equation using algebraic operations.

Front

What is the relationship between the measures of angles in a triangle?

Back

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