Unit 1: Segment Addition and Midpoint

Front

What is the Segment Addition Postulate?

Back

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

Front

If A is between B and C, what is the correct Segment Addition statement?

Back

AB + BC = AC.

Front

Given points A, B, and C are collinear and B is between A and C, if AB = 7 and BC = 5, what is AC?

Back

AC = AB + BC = 7 + 5 = 12.

Front

If B is between A and C and AB = 6, BC = 4, what is AC?

Back

AC = AB + BC = 6 + 4 = 10.

Front

What does it mean for points to be collinear?

Back

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

Front

If L is between M and K, and ML = 3 and LK = 5, what is MK?

Back

MK = ML + LK = 3 + 5 = 8.

Front

If DE = 12 and EF = 5, what is DF?

Back

DF = DE + EF = 12 + 5 = 17.

Front

What is the definition of a midpoint?

Back

A midpoint is a point that divides a segment into two equal parts.

Front

If A is the midpoint of segment BC, and BC = 10, what is AB?

Back

AB = 5, since A divides BC into two equal segments.

Front

If AB = 4 and AC = 10, what is BC?

Back

BC = AC - AB = 10 - 4 = 6.
