What does the Segment Addition Postulate state?

Back

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

Front

If AB = 3x + 2 and BC = 4x - 5, what is AC if A, B, and C are collinear?

Back

AC = AB + BC = (3x + 2) + (4x - 5) = 7x - 3.

Front

If AB = 10 and BC = 15, what is AC?

Back

AC = AB + BC = 10 + 15 = 25.

Front

If point D is between points A and C, and AD = 4 and DC = 6, what is AC?

Back

AC = AD + DC = 4 + 6 = 10.

Front

If AB = 2x + 3 and AC = 5, what is BC if B is between A and C?

Back

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