Remediation LQ: 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

Using the Segment Addition Postulate, what is the correct equation relating the segments AM, MB, and AB?

Back

AM + MB = AB.

Front

What are coplanar points?

Back

Coplanar points are points that lie on the same plane.

Front

What are collinear points?

Back

Collinear points are points that lie on the same straight line.

Front

If AM = 5 and MB = 7, what is AB?

Back

AB = AM + MB = 5 + 7 = 12.

Front

Write an equation that models the lengths: 2x - 2 + 6 = 3x + 2. What is x?

Back

x = 4.

Front

What does it mean for points to be collinear in relation to the Segment Addition Postulate?

Back

Collinear points can be used to apply the Segment Addition Postulate as they lie on the same line.

Front

If AB = 10 and AM = 4, what is MB?

Back

MB = AB - AM = 10 - 4 = 6.

Front

What is the relationship between segments in a straight line?

Back

The lengths of the segments can be added together to find the total length of the line segment.

Front

If points A, B, and C are collinear, and AB = 3x + 1 and BC = 2x + 4, what is AC?

Back

AC = AB + BC = (3x + 1) + (2x + 4) = 5x + 5.
