If three points lie on a straight line, then the points are collinear - Converse - If three points are collinear, then they lie on a straight line. Inverse - If three points are not collinear, then they don't lie on a straight line. Contrapositive - If three points don't lie on a straight line, then they are not collinear.
If the lines form a right angles, then the lines are perpendicular. Converse - If the lines are perpendicular, then they form right angles. Inverse - If the lines are not perpendicular, then they don't form right angles. Contrapositive - If the lines don't form right angles, then they are not perpendicular.
