Segment Addition Postulate

Front

What is the Segment Addition Postulate?

Back

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

Front

What does 'collinear' mean?

Back

Collinear points are points that lie on the same straight line.

Front

Which points are collinear: A, B, C or D, B, E?

Back

D, B, E are collinear.

Front

What is a postulate?

Back

A postulate is a statement accepted as true without proof; a rule.

Front

What is a ray in geometry?

Back

A ray is part of a line that has a starting point but extends infinitely in one direction.

Front

How do you find the length of a segment?

Back

Use the distance formula or segment addition.

Front

Write an equation using the Segment Addition Postulate for points A, B, and C.

Back

If B is between A and C, then AB + BC = AC.

Front

What is the difference between a line segment and a ray?

Back

A line segment has two endpoints, while a ray has one endpoint and extends infinitely in one direction.

Front

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

Back

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

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.
