After you define linear pairs make a statement that they are supplementary with the reason “Linear pairs are supplementary” or “Linear Pair Postulate.” You may also say that the angles add to = 180 by Linear Pair Postulate instead of stating that they are supplementary 1st. If two angles form a linear pair, then they are supplementary. problem solving that involves the linear pair postulate and vertical for each of these properties and also an example. Using the Linear Pair Postulate The Linear Pair Postulate states: “If two angles form a linear pair, then the angles are supplementary .” Example P Q S R 38° m PQR 1 m SQR 5 180º 38º 1 m SQR 5 180º m SQR 5 180º 2 38º m SQR 5 142º 2.2 2.2 1 and are ... linear pair postulate c. substitution d. congruent supplements theorem e. congruent complements theorem f. definition of congruence g. given We know that opposite rays form a straight angle and a straight angle has 180°. Given: 2. m<1 + m<4 = 180˚ 2. The last thing to do before starting on the proof of the vertical angles theorem is to introduce the linear pair postulate. m∠1 + m∠2 = 180∘.
