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 = 7 and BC = 15, what is AC?

Back

AC = AB + BC = 7 + 15 = 22.

Front

If GH = 8 and HI = 17, find GI.

Back

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

Front

If JK = 7 and LJ = 20, find KL.

Back

KL = LJ - JK = 20 - 7 = 13.

Front

In a line segment, if T is the midpoint of SU, what is the relationship between ST and TU?

Back

ST = TU, since T is the midpoint.

Front

If BC + CD = BD, what does this represent?

Back

This represents the Segment Addition Postulate, where B, C, and D are collinear points.

Front

What is the formula to find the length of a segment if you know the lengths of its parts?

Back

Length of the whole segment = Sum of the lengths of its parts.

Front

If AB = 10 and BC = 5, what is AC?

Back

AC = AB + BC = 10 + 5 = 15.

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

What does it mean for a point to be a midpoint?

Back

A midpoint divides a segment into two equal parts.
