Understanding Rays, lines, segments, and collinear

Given Line ABC, Which of the following is a ray opposite to ray BC?

• CB

• BA

• BD

• AB

Which set of points are collinear?

• A, B, D

• A, C, E

• B, C, D

• A, D, C

Which of the following is a correct way to name a line passing through points A and D?

• AD (with a single arrow)

• AD (with a double arrow)

• AD (with a line over it)

• AD

Which of the following is another correct notation for the line passing through points C and B?

• CB (with a double arrow)

• CB (with a single arrow)

• CB (with a line over it)

• CB

Which of the following is a segment on the line containing points A and D?

• AD (with a single arrow)

• AD (with a double arrow)

• AD (with a line over it)

• AD

Given the line, Is point B between points A and D?

• Yes, because A, B, and D are collinear and B is between A and D.

• No, because B is not between A and D.

• Yes, because B is not collinear with A and D.

• No, because A and D are not on the same line as B.

Which of the following statements is true about opposite rays?

• Opposite rays have the same initial point and go in the same direction.

• Opposite rays have the same initial point and go in opposite directions.

• Opposite rays have different initial points.

• Opposite rays are always parallel.

Which of the following is NOT a correct way to name a line?

• AB (with a double arrow)

• BA (with a double arrow)

• AB (with a line over it)

• CD (with a double arrow)

Which of the following is a correct way to name a segment between points B and C?

• BC (with a line over it)

• BC (with a double arrow)

• BC (with a single arrow)

• BC

If points A, B, and C are collinear and B is between A and C, which of the following is true?

• AB + BC = AC

• AB = AC + BC

• AC = AB - BC

• AB = BC
