Question  Answer 
Every time you use a trigonometric function, the triangle must be a(n)...  Right triangle 
The side on the opposite side of a given angle is called "opposite."  triangel.jpg (image/jpg) 
The side of a triangle that is the only side touching the given angle (besides the hypotenuse)is the "adjacent."  triangel.jpg (image/jpg) 
The longest side of a given triangle is the "hypotenuse." (It is never called adjacent.)  triangel.jpg (image/jpg) 
Tangent  Abbreviated as "tan" is opposite divided by adjacent. 
Sine  Abbreviated as "sin" is opposite divided by hypotenuse. 
Cosine  Abbreviated as "cos" is adjacent divided by hypotenuse. 
Trigonometric Tables  Tables that help you figure out how many degrees an angle is after you find out the sin, cos, or tan.
