Segment and Angle Addition Postulate

Front

What are Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

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 are Adjacent Angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

What are Supplementary Angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are Complementary Angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

If angle A is 39 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle is 141 degrees.

Front

If angle A is 51 degrees, what is the measure of its complementary angle?

Back

The complementary angle is 39 degrees.

Front

If B is between A and C and AB = 12 and BC = 16, what is AC?

Back

AC = 28.

Front

If KL = 6 and KM = 12, what is ML?

Back

ML = 6.

Front

What is the relationship between Vertical Angles?

Back

Vertical angles are always equal.
