Segment and Angle Addition

Front

What is Segment Addition Postulate?

Back

If point B is between points A and C, then AB + BC = AC.

Front

What is Angle Addition Postulate?

Back

If point B is in the interior of angle AOC, then m∠AOB + m∠BOC = m∠AOC.

Front

If T is the midpoint of segment SU, what does that imply about ST and TU?

Back

ST = TU.

Front

How do you find the measure of an angle if you know the measures of the adjacent angles?

Back

Use the Angle Addition Postulate: m∠A + m∠B = m∠C.

Front

What is the formula to find the length of a segment given its endpoints?

Back

Length = |x2 - x1|.

Front

If AC = 48 and AB = 16, what is the length of BC?

Back

BC = AC - AB = 48 - 16 = 32.

Front

What does it mean for a point to be a midpoint?

Back

A midpoint divides a segment into two equal parts.

Front

If BC + CD = BD, what does this represent?

Back

This represents the Segment Addition Postulate.

Front

What is the measure of angle QSR if it is given as 26 degrees?

Back

m∠QSR = 26°.

Front

If x = 3 in the equation for segment lengths, what does that represent?

Back

It represents the length of a segment or part of a segment.
