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.

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

Back

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

How do you find the length of a segment when given two other segments?

Back

You can use the Segment Addition Postulate to add the lengths of the two segments together.

Front

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

Back

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

Front

What is the formula to find the length of a segment when given the total length and one segment?

Back

Length of the unknown segment = Total length - Length of the known segment.

Front

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

Back

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

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 you know the value of x in a segment equation, how can you find the lengths of the segments?

Back

Substitute the value of x into the equations for the segments to find their lengths.

Front

If AC = 22, what could be the possible lengths of AB and BC if AB = 11?

Back

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

Front

What is the relationship between the lengths of segments in a straight line?

Back

The sum of the lengths of the segments must equal the length of the entire segment.
