Does every ray contain a line segment?

A. Only if there are three points on the ray

B. Yes, because all you need for a line segment is one point

C. No, because an element can't be two things

D. No, because the end point is really an arrow

E. Yes, because every ray needs two points to define it

F. No because the points are busy making a ray

7. Does every line contain a ray?

A. Yes, because a ray and a line both have arrows.

B. No, because the two points necessary for a ray are making a line

C. Yes, because a ray needs two points to exist, which are always part of a line.

D. Sometimes, if the arrows are in the right places

E. No, because lines don't end and a ray needs an endpoint

F. Only if the line has three points on it

Do two rays always define a plane?

A. No, because a ray can't be used to define a plane

B. Yes, because we need three points

C. No, because two rays might only make one line

D. Yes, because rays can be extended into lines

E. No, because there aren't enough points

F. Yes, because it's the number of points that matter

9. If I have an angle between 10 and 170 degrees, do I have a plane?

A. Only if you have an additional point not on the angle

B. Yes, because a ray always defines a plane

C. No, because there aren't enough points

D. Yes, because angles are big

E. No, because rays cannot be extended into lines

F. Yes, because that means you have two lines that meet at a single point
