PARALLEL LINES Make sure you know how to identify the different types of angles formed when two lines are cut by a transversal: The angle pairs {2, 8} and {3, 7} are alternate interior angles—you can remember this because they form a sort of “Z” shape or reversed “Z” shape. opposite sin hypotenuse q= hypotenuse csc opposite q= adjacent cos hypotenuse q= hypotenuse sec adjacent q= opposite tan adjacent q= adjacent cot opposite q= Unit circle definition For this definition q is any angle. The formality of developing geometry from axioms is often replaced by a breezy informal treatment of ge-ometric highlights. but first you need to be familiar with a few terms. Note that a proof for the statement “if A is true then B is also true” is an attempt to verify that B is a logical result of having assumed that A is true. Printable geometry formulas cheat sheet.
