A reference angle for a given angle in standard position is the positive acute angle formed by the $x$-axis and the terminal side of the given angle. Reference angles, by definition, always have a measure between 0 and . Due to the periodic nature of the trigonometric functions, the value of a trigonometric function at a given angle is always the same as its value at that angle's reference angle, except when there is a variation in sign.
The AA Similarity Postulate. The AA (angle angle) similarity postulate states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. Example of use in a proof (us the diagram on the right for the given and what needs to be proven) :
