How is Trigonometry used?

Special functions are there, which are simply one side of a triangle divided by another.

Terms used in Trigonometry

✓  LEGS – the two sides of a right triangle which form the right angle.
✓  Hypotenuse is the third side which is opposite the right angle. It is always same.
✓  Theta θ  is used to represent the angle.
✓  Depending on which angle we’re referring to at the time, the designations of opposite and adjacent can change.

Sides of a Triangle in Trigonometry

✓  The side that doesn’t help make up the angle – opposite side
✓  The side which is always one of the sides of the angle – adjacent side
✓  They are simply one side of a triangle divided by another like the ratios that we get like Sine, Cosine and Tangent, which  are often written as Sin, Cos and Tan.
