... located at the origin and one ray is on the positive x-axis. The ray on the x-axis is called the initial side and the other ray is called the terminal side. If the terminal side of an angle lies "on" the axes (such as 0º, 90º, 180º, 270º, 360º ), it is called a quadrantal angle. The angle shown at t ...

... It is important to realize that it does not matter what point you select on the terminal side of the angle the trigonometric ratios will be the same because the triangles are similar. The triangle with its vertex at P1 is similar to the triangle with its vertex at P2 and the length of the sides are ...

Summary of Objectives
... Obj: Apply theorems about inequalities in triangles. (The sum of any two sides of a triangle is greater than the third. If two sides of a triangle are unequal, then the larger angle lies opposite the longer side. If two angles of a triangle are unequal, then the longer side lies opposite the larger ...

Understanding Angles
... •In the first quadrant the principal angle and related acute angle are always the same •In the second quadrant we get the principal angle by taking (180º - related acute angle) •In the third quadrant we can get the principal angle by taking (180º + related acute angle) •In the fourth quadrant we can ...
