08.06.25 1.2/3 - Segment Addition Postulate and Midpoint

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

What is a midpoint?

Back

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

Front

If G is the midpoint of segment FH and FH = 30, what is FG?

Back

FG = 15.

Front

If R is the midpoint of QS and RS = 2x - 4, ST = 4x - 1, and RT = 8x - 43, how do you find QS?

Back

Set RS + ST = QS and solve for x, then calculate QS.

Front

What does it mean if BC + CD = BD?

Back

It means that the length of segment BD is equal to the sum of the lengths of segments BC and CD.

Front

If RM = 6 and R is the midpoint, what is the length of segment RM?

Back

RM = 3.

Front

How do you calculate the length of a segment given its midpoint?

Back

Double the length of one half of the segment.

Front

If segment AB = 24 and point C is the midpoint, what is AC?

Back

AC = 12.

Front

What is the formula to find the length of a segment using its endpoints?

Back

Length = |x2 - x1| for horizontal segments or |y2 - y1| for vertical segments.

Front

If segment PQ = 40 and point R is the midpoint, what is PR?

Back

PR = 20.
