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 = 5 and BC = 6, what is AC?

Back

AC = AB + BC = 5 + 6 = 11.

Front

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

Back

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

Front

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

Back

The formula is: Length of the whole segment = Length of segment 1 + Length of segment 2.

Front

If AB = 11 and BC = 22, what is AC?

Back

AC = AB + BC = 11 + 22 = 33.

Front

How do you solve for x in a segment addition equation?

Back

Isolate x by rearranging the equation to one side.

Front

If DE = 6 and EF = x, what is the equation for DF?

Back

DF = DE + EF, so DF = 6 + x.

Front

What does it mean if two segments are congruent?

Back

Two segments are congruent if they have the same length.

Front

If AB + BC = AC, what can you conclude about the points A, B, and C?

Back

Point B lies between points A and C.

Front

If AB = 11 and AC = 33, what is BC?

Back

BC = AC - AB = 33 - 11 = 22.
