Segment Addition, Midpoint and Segment Bisector

Front

What is the Segment Addition Postulate?

Back

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

Front

What is a midpoint?

Back

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

Front

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

Back

To find the length of a segment, subtract the coordinates of the endpoints and take the absolute value.

Front

What is a segment bisector?

Back

A segment bisector is a point, line, or ray that divides a segment into two equal parts.

Front

If OQ = 32 and PO = 4x, how do you find x?

Back

Set PO equal to half of OQ: 4x = 32/2, then solve for x.

Front

What is the formula for finding the length of a segment on a number line?

Back

Length = |x2 - x1|, where x1 and x2 are the coordinates of the endpoints.

Front

What does it mean for a point to be between two other points on a line segment?

Back

It means that the distances from the first point to the middle point and from the middle point to the last point add up to the total distance between the first and last points.

Front

How can you determine if a point is the midpoint of a segment?

Back

A point is the midpoint if it is equidistant from both endpoints of the segment.

Front

What is the relationship between a segment bisector and the segments it divides?

Back

A segment bisector creates two segments that are equal in length.

Front

If AC = 22 and C is the midpoint, what is the length of AB?

Back

AB = 2 * AC = 2 * 22 = 44.
