first draw a right angled triangle
the side opposite to right angle (90 degrees) is called the hypotenuse
the other two sides are called legs .. the base side of the triangle . , the perpendicular side to the base are two legs.
let us take the base side { adjacent side} as " side a" ,, the perpendicular to the base side { opposite side} take as " b" always. the hypotenuse as side "c"
now the angle formed between the side "a" and the side ""c"" as then ,
Sine = b / c {sin }
cosine = a / c [cos]
tangent = b / a [tan]
the converse of sine is cosecant [cosec]
cosine is secant [ sec]
tangent is cotangent [ cot ]
using this basic you can do the drawings correctly.
{{{{{{Always the side to opposite to the angle is opposite side ,. the other side is the adjacent side , the side opposite to 90 degrees is hypotenuse }}}}} ---== this is important . NOW YOU CAN DO EASILY
