How to draw planes in geometry?

Question

How do I draw planes R & M intersecting at line CD?

how do I draw plane R containing non-collinear points A, B, C

how do I draw plane M containing D not on line l and line l

how do I draw plane M containing parallel lines AB and CD

Answer 1

Here is the first answer but this answer form doesn't allow much memory use so I can't draw the others.

Non-collinear points are just 3 points that are not all in a straight line.

Answer 2

First you want to draw the intersection cd.

Measure and draw the shapes in reference to it.
