  1. 2. Trigonometry <ul><li>The relationships between the angles and the sides of the right triangle are expressed in terms of trigonometric ratios. </li></ul>:                                                                                                  
  2. 3. How to find the positive acute reference angle <ul><li>The reference angle is the positive acute angle on the X-Y plane has a reference angle, Which is always between 0 and 90 degrees. A reference angle always uses the X- axis as it’s frame of reference </li></ul>
  3. 4. The Unit Circle <ul><li>The Unit Circle is a tool used in understanding sines and cosines of angles found in right triangles. It is so named because its radius is exactly one unit in length, usually just called &quot;one&quot;. The circle's center is at the origin, and its circumference comprises the set of all points that are exactly one unit from the origin while lying in the plane </li></ul>
  4. 5. ConterminalB angle <ul><li>Conterminal angles are angles, which share a common terminal side. There are two sides of an angle: the initial side and the terminal side. The initial side is the ray where the measurement of an angle starts. The terminal side is the ray where the measurement of an angle stops </li></ul>
