Segment Addition Postulate

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

If AB = 60 and AC = 78, what is BC?

Back

BC = AC - AB = 78 - 60 = 18.

Front

Given JK = 7 and LJ = 20, how do you find KL?

Back

Use the Segment Addition Postulate: KL = LJ - JK = 20 - 7 = 13.

Front

If DE = 6 and EF = 5, what is DF?

Back

DF = DE + EF = 6 + 5 = 11.

Front

What is the formula to find the length of a segment?

Back

Length of a segment = Distance between two endpoints.

Front

If AB = 17, BC = 46, what is AC?

Back

AC = AB + BC = 17 + 46 = 63.

Front

How do you solve for x in a segment equation?

Back

Set up the equation based on the Segment Addition Postulate and solve for x.

Front

If AB + BC = AC, what does this imply about points A, B, and C?

Back

It implies that point B lies between points A and C.

Front

What is the relationship between segments AB, BC, and AC if AB = 60 and AC = 78?

Back

BC = AC - AB = 78 - 60 = 18.

Front

If two segments are equal, what can be said about their lengths?

Back

Their lengths are the same.
