The following statements are true, except:

• If two planes intersect then, their intersection is a line

• If a line is on the plane then, the points on the line are not on the plane

• If lines AB and CD intersect, then they intersect at exactly one point

• If two points are not on the line, then they are non-collinear.

All of the statements are true, EXCEPT

• If x = y, then y = x

• 3(a + b) = 3a + 3b

• If a = b and b = c then a = c

• 2 + ( a - b) = 2a - 2b
