Katie plots two points, K and L, on a paper and joins them using a straight line, as shown. (I WILL POST THE IMAGE IN THE COMMENTS)
Which statement is true?
a) Line KL is on the same plane as the points K and L because a postulate states that if two points lie in a plane then the line joining them also lies in that plane.
b) Line KL and the points K and L lie on different planes because a postulate states that the measure of a straight angle is two right angles.
c) Line KL and the points K and L lie on different planes because a theorem states that a line extends on both sides of a plane.
