Segment Addition and Midpoint Practice

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

Define a midpoint of a segment.

Back

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

Front

If AC = 22 and AB = 7, what is BC?

Back

BC = 15 (using the Segment Addition Postulate: AC = AB + BC).

Front

How do you find the length of a segment given its endpoints?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the formula for finding the midpoint of a segment with endpoints (x1, y1) and (x2, y2)?

Back

Midpoint M = ((x1 + x2)/2, (y1 + y2)/2).
