Question

1. if (b) is between (a) and (c), then (ab + bc=ac)

segment addition property
definition of midpoint
addition property
substitution property

Explanation:

The Segment Addition Property states that if a point B lies between two points A and C on a line segment, the sum of the lengths of the two smaller segments AB and BC is equal to the length of the larger segment AC. The other options do not match this geometric relationship. The Definition of Midpoint refers to a point that divides a segment into two equal parts. The Addition Property is a more general algebraic property not specific to line - segments. The Substitution Property involves replacing one quantity with an equal quantity.

Answer:
