Segment Addition Postulate

Front

What is the Segment Addition Postulate?

Back

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

Front

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

Back

AC = AB + BC = 12 + 16 = 28.

Front

If HJ = 7x - 27, what is the value of x when HJ = 4?

Back

4 = 7x - 27; x = 7.

Front

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

Back

A midpoint divides a segment into two equal parts.

Front

If T is the midpoint of SU and SU = 6, what is ST?

Back

ST = 3, since T divides SU into two equal segments.

Front

Given that C is between A & B, which Segment Addition statement is correct?

Back

AC + CB = AB.

Front

If DF = 9x - 39 and EF = 58, what is the value of x?

Back

58 = 9x - 39; x = 11.

Front

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

Back

Length = |x2 - x1|, where x1 and x2 are the endpoints.

Front

If A is at 2 and B is at 10, what is the length of AB?

Back

AB = |10 - 2| = 8.

Front

If the length of segment AB is 15 and point C is between A and B, what can we say about AC and CB?

Back

AC + CB = 15.
