You are watching: What is the difference between linear pair and supplementary angles
The angles can be either adjacent (share a usual side and a common vertex and also are side-by-side) or non-adjacent.Example 1. Provided m 1 = 45° and m 2=135° recognize if the 2 angles space supplementary.45° + 135° = 180° because of this the angles space supplementary.We will usage the adhering to facts to aid us identify if 2 angles are supplementary.
A linear pair is 2 angles that are surrounding and kind a line. The angle measure of a line is 180°If two angles type a linear pair then they are supplementary.
Example 2: the angles type a line (linear pair) therefore they room supplementary
Example 3: the angles deserve to be non-adjacent as lengthy as their sum is 180°
110°+ 70° = 180° The sum is 180° as such they room supplementary.Example 4: 1 and also 2 form a linear pair for this reason m 1 + m 2 = 180° as such the angles are supplementary.

How countless other direct pairs have the right to you watch in the diagram?
m 2 + m 3 = 180°m 3 + m 4 = 180°m 1 + m 4 = 180°Remember that linear pairs are supplementary and also that 2 intersecting currently will type 4 bag of supplementary angles.Geometry & Algebra: uncover the value of x the uncover the m ABD and also m DBC.
Write one equation(4x +6) ° + (11x - 6)°= 180°Identify like terms(4x +6) ° + (11x - 6)°= 180°Combine choose terms4x + 11x +6 - 6 = 180°15x + 0 = 180°The zero is unnecessary
Divide both sides by 15x = 12m ABD = 4x + 6 = 4(12)+6 = 54°m DBC = 11x - 6 = 11(12) -6 = 126°check her answer54° + 126° = 180°Sum it up: Supplementary angles space two angles whose amount is 180°. A straight pair (two angles that type a line) will always be supplementary. The two angles have the right to be surrounding or non-adjacent.
