What is a line?

• a straight path of points that goes on and on in two directions

• an endless flat surface

• an exact location in space

• lines that never intersect

Find AC

• 7

• 8

• 22

• 23

Are the points shown collinear?

• Yes

• No

Choose the points that are collinear.

• A, B, and C

• A, C, and D

• A, E, and F

• B, C, and D

Use the picture to write the correct Segment Addition statement.

• AB + BC = AC

• BC + BA = BC

• BA + AC = BC

• A + B = C
