In the following questions, fill in … Linear Pair Theorem: If two angles are a linear pair (consecutive angles with a shared wall that create a straight line), then their measures will add to equal 180° Example: Given: Prove: ∠ + ∠ =180° Reasons ∠ & ∠ are a linear pair Given ∠ + ∠ =180° Linear Pair Theorem Linear Pair of Angles A pair of adjacent angles formed by intersecting lines. If two angles form a linear pair, the angles are supplementary. The following practice questions ask you to solve problems based on linear pairs. Linear Pair A linear pair is a pair of adjacent angles formed when two lines intersect. Linear pairs of angles are supplementary. Two Angles are Supplementary when they add up to 180 degrees. (A straight angle measures 180 degrees.) Linear Pain is a set of two angles that are adjacent to each other, formed by two intersecting lines, and the measure of straight angle should be 180 degrees. So, In a linear pair, there are two angles who have. Here, these angles are in linear pair as. In such a case, all adjacent angles form a linear pair. ∠1 and ∠3 are not vertical angles (they are a linear pair). (noun) The solution of a linear equation in two variables is a pair of values, one for x and the other for y, which makes the two sides of the equation equal. Basically, a linear pair of angles always lie on a straight line. A linear equation is an equation in which the variable (s) is (are) with the exponent 1 Example: 2x = 23 2 x = 23 x−y =5 x − y = 5 4.
