Use the above figure to answer the following questions.
a. name three points that are collinear

b. name four coplanar points

c. what is the intersection of plane p and plane r?

d. name a point that lies on both plane p and plane r

e. name plane p and two more ways

A) "Co-linear" means "on the same line: So, A, D and B

B) "Co-planar" means "on the same plane": So, A,B,C,D (or F,D,B,G) (or A,D, B, E) there are lots that work

C) Plane P and Plane R intersect along the line in the middle: Line AB.

D) Any point on both planes will work; also we know by definition that it will be on the intersecting line. So any of A,B or D.

E) To name the plane we need three points on it BUT these point can't be co-linear or we could be naming another plane as well. So we pick three points on P that aren't in line with each other: C,D, E works (or C,B,E) etc.
