What is the purpose of the proclamation that Shaw reads from the Confederate Congress? (b) Two obtuse angles can form a linear pair (c) Two right angles can form a linear pair (d) One obtuse angle and one acute angle cannot form a linear pair. Proof. The Linear Pair Theorem states that two angles that form a linear pair are supplementary; that is, their measures add up to 180 degrees. The following practice questions ask you to solve problems based on linear pairs. STUDY. The relations between angles are characterized by the pairs of angles as listed below: 1. When there are three lone pairs (m=1, n=3 or AX 3 E 2), the lone pairs … © copyright 2003-2021 Study.com. But and form a linear triple and they are a set of arbitrary angles forming a linear triple. When there are two lone pairs (m=3, n=2 or AX 3 E 2), each lone pair occupies one of the three equatorial positions. Supplementary angles are angles that sum to 180 degrees. You can always check your work by adding the two measures to see if they add to equal 180 degrees.
