Kelly drew four points A, B, C, and D in her notebook.
A straight line joins points A and C. Another straight line joins A and B. A point D is located on the left of the line AB
Kelly made the following statements about the points.
Statement 1: There is at least one more point on the plane containing points B and C.
Statement 2: One plane contains segment AC and Point D.
Which chart best justifies Kelly's statements?
things are ambiguous.
what does "on the left" of line AB mean?
Is AB basically horizontal, and D in on AB toward the left? Or is AB basically vertical and D is not on the line at all, but left of it?
#1. how does a point contain B and C?
#2. true, since 3 points define a plane.
a little proofreading would help.
