Please help me answer these!!

Step-by-step explanation:

Line WQ could also be called Line QW (These are uppercase letters, two points that are on the line and should have a line symbol across the top of them) and also lines are often named with a single small letter, in this case, Line g.

You can name a plane by using three non collinear points on the plane with a little ane symbol in front (looks kind of like a parallelogram) *planesymbol* RST

(or RQT or SQT)

R, Q, and S are collinear (all on the same line) and T (or W) is a fourth point that is not on the same line as the other three points.

W is off the plane that R, S, and T are in.

  the correct choice is marked
