Glossary Term amplitude Definition For functions of the form y = A sin kα or y = A cos kα, the amplitude is A . analytic geometry The study of coordinate geometry from an algebraic perspective. A figure formed by two rays with a common endpoint. In the figure, ∠RST is formed by rays SR and ST with the common endpoint (or vertex) S. angle angle bisector A ray whose endpoint is the vertex of the angle and is located in the interior of the angle. It separates a given angle into two angles with equal measure. In the figure, PW is the angle bisector of ∠P. angle bisector of a triangle A segment that separates an angle of a triangle into two congruent angles. angle of depression The angle formed by a horizontal line of sight and a line of sight below it.
