Line Terms & Addition Segment Postulate

Front

What are coplanar points?

Back

Coplanar points are points that lie on the same plane.

Front

Identify 4 coplanar points from the following: D, E, F, G, H.

Back

G, D, E, F are coplanar points.

Front

What are collinear points?

Back

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

Front

Identify 3 collinear points from the following: D, E, F, G, H.

Back

D, E, F are collinear points.

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

If AC = 32, what is the measure of BC if AB = 15?

Back

BC = 32 - 15 = 17.

Front

If AC = 48 and AB = 32, what is the length of BC?

Back

BC = 48 - 32 = 16.

Front

If the length of PR is 45 units and PQ = 42, what is the length of QR?

Back

QR = 45 - 42 = 3.

Front

What is the formula to find the length of a segment?

Back

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

Front

How do you determine if points are coplanar?

Back

Points are coplanar if a single plane can contain all of them.
