The problem expects that you know the definition of supplementary. All linear pairs of angles are supplementary and therefore. Geometric Definition of Supplementary: Two angles are supplementary if, when placed adjacent to each other with one side in common, their non-common sides form a straight line. You can put this solution on YOUR website. The two angles can be adjacent or non-adjacent. You can triple check that two angles are a linear pair by seeing if they add up to 180 degrees. A linear pair (two angles that form a line) will always be supplementary. Sum it up: Supplementary angles are two angles whose sum is 180°. Geometry & Algebra: find the value of x the find the m ABD and m DBC. Theorem If two congruent angles are supplementary, then each is a right angle. Remember that linear pairs are supplementary and that 2 intersecting lines will form 4 pairs of supplementary angles. Geometric mean The value of x in proportion a/x x/b where a, b, and x are positive numbers (x is the geometric mean between a. Adjective supplementary, for its part, refers to that. How many other linear pairs can you see in the diagram? The geometric figures that are formed by two rays, which share origin (vertex), are called angles. If two angles form a linear pair then they are supplementary.Įxample 2: the angles form a line (linear pair) therefore they are supplementaryĮxample 3: the angles can be non-adjacent as long as their sum is 180°ġ10°+ 70° = 180° The sum is 180° therefore they are supplementary.ġ and 2 form a linear pair so m 1 + m 2 = 180° therefore the angles are supplementary.A linear pair is two angles that are adjacent and form a line.
