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 the length of BC?

Back

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

Front

If GH = 8 and HI = 17, what is the length of GI?

Back

GI = GH + HI = 8 + 17 = 25.

Front

If JK = 7 and LJ = 20, what is the length of KL?

Back

KL = LJ - JK = 20 - 7 = 13.

Front

What is the formula to find the length of a segment when given two other segments?

Back

If A, B, and C are points on a line, then AC = AB + BC.

Front

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

Back

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

Front

If AB = 72 and AC = 78, what is the length of BC?

Back

BC = AC - AB = 78 - 72 = 6.

Front

What does it mean for a point to be 'between' two other points on a line segment?

Back

A point is 'between' two other points if it divides the segment into two smaller segments.

Front

If AB = 60 and BC = 18, what is the length of AC?

Back

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

Front

If the total length of a segment is 30 and one part is 12, what is the length of the other part?

Back

The length of the other part = Total length - One part = 30 - 12 = 18.
