bullet::::- "adjacent angles", often abbreviated as "adj. ∠s", are angles that share a common vertex and edge but do not share any interior points. in other words, they are angles that are side by side, or adjacent, sharing an "arm". adjacent angles which sum to a right angle, straight angle or full angle are special and are respectively called "complementary", "supplementary" and "explementary" angles (see "combine angle pairs" below).









































a transversal is a line that intersects a pair of (often parallel) lines and is associated with "alternate interior angles", "corresponding angles", "interior angles", and "exterior angles".

the sum of the measures of the interior angles of a triangle in euclidean space is always 180 degrees. this fact is equivalent to euclid's parallel postulate. this allows determination of the measure of the third angle of any triangle given the measure of two angles. an "exterior angle" of a triangle is an angle that is a linear pair (and hence supplementary) to an interior angle. the measure of an exterior angle of a triangle is equal to the sum of the measures of the two interior angles that are not adjacent to it; this is the exterior angle theorem. the sum of the measures of the three exterior angles (one for each vertex) of any triangle is 360 degrees.
