27. Draw and label a figure for each relationship.

28. plane R contains lines AB and DE, which intersect at point P. Add point C on plane R so that it is not collinear with AB or DE.

29. Draw and label a figure for each relationship. plane R contains lines AB and DE, which intersect at point P. Add point C on plane R so that it is not collinear with AB or DE. QR on a coordinate plane contains Q(-2, 4) and R(4, -4). Add point T so that T is collinear with these points.
