Its a branch of mathematics which involves lengths and angles of triangle.If 1 angle is 90 degree and the other is known then the third is fixed bcoz sum of all angles of Δ is 180 degree.
This are the formula used in trigonometry,
SinA=perpendicular/hypotenuse
CosA=base/hypotenuse
TanA=perpendicular/base.
It is used in many fields like in astronomy,satellite navigation,etc.
