 Is
it possible for two planes to meet in just
one point? NO
 Can two planes contain the same line? YES
 Can three planes meet in just one point? YES
 If three points do not lie on the same line,
how many different planes can contain those
three points? ONE

 True
or false: Two lines are parallel if they
do not intersect.
 True or false: If two distinct lines are
perpendicular to a third line, then they are
parallel.
 True
or false: Two lines are parallel if they
do not intersect. FALSE (could be skew…
statement is true in a plane only – 2D)
 True or false: If two distinct lines are
perpendicular to a third line, then they are
parallel. FALSE (true in 2D on a plane, but
not in 3D)
