    1. What does it mean for points to be collinear? coplanar? 2. What do you call two rays that have the same endpoint and form a line? 3. Can a line intersect a plane in only two points? Explain. 4. How do you name geometric figures?

    1. collinear = points on the same line coplanar = points in the same plane

    2. remember the other problem? two rays w/ the same endpoint and form a line are opposite rays

    so 2 is two rays w/ the same endpoint and form a line are opposite rays

    3. to figure this one out, try drawing a line through a plane and seeing how many times it can intersect

    only once. ITs like If you put a pencil through a piece of paper, it's only going to cross the paper in one place

    4. I'm not really sure, it would depend on which geometric figure you're talking about

    as an example, you name a line by picking 2 points, you name an angle by picking either 3 points, or the vertex, etc.

    this is mainly on plains and points like that

    well, in short: point: one letter line/line segment: two points plane: three points angle: three points, or the vertex ray: two points, with the endpoint first

    So that could be the answer?

    well, it's a start, I would flesh it out with more details, and in complete sentences, etc.
