So I choose, as many texts do, to treat it as a postulate. Linear Pair Postulate: If two angles form a linear pair, then they are supplementary. If two angles form a linear pair, then they are supplementary; that is, the sum of their measures is 180 degrees. Given: <1 and <3 are vertical angles Prove: <1 <3 Proof: Statements Reasons 1. A. Paragraph Proof : Because ∠5 and ∠6 are a linear pair, the linear pair postulate says that ∠5 and ∠6 are supplementary. I remind the students how we used the linear pair postulate to prove the vertical angles theorem, which we will (by the way) be using to prove theorems in this lesson. From the theorem’s proof, you would see that this theorem is the combination of both the Triangle Sum Theorem and the Linear Pair Postulate.

Alternate Interior Angles of Parallel Lines Theorem (AIP) IF two lines are parallel, THEN the alternate interior angles are congruent. ∠1 and ∠2 form a linear pair, so ∠1 and ∠2 are supplementary and m∠l + m∠2 = 180°. What is the reason for Statement 2 of the two-column proof? Using the Angle Addition Postulate and definition of Deductive Reasoning and Proof. By substitution, m∠1+m∠3=180° , so ∠1 and ∠3 are supplementary by the definition of supplementary. To play this quiz, please finish editing it. 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.
