  6. The special triangles are two triangles that are very easy to work with in trigonometry. The angles are simple to calculate and their sides are easy to determine, so the trig ratios associated with them are easily expressed.

  7. Definition. An angle is a form of geometrical shape, that is constructed by joining two rays to each other at their end-points. The angle can also be represented by three letters of the shape that define the angle, with the middle letter being where the angle actually is (i.e.its vertex).
