Hi

Trigonometry is made up of two words i. e

--------------------) trigonon

--------------------) metron

Now,

• trigonon means triangle .

• And metron's  meaning is measurement .

So,

Trigonometry is the measurement of triangle

A triangle has 6  parts i. e

• 3-sides and

• 3-angles

Trigonometry  gives us relationship between sides and angles of a triangle.

In a right angle triangle,

Trigonometric ratios are given by

--------------------) sinθ=OppositeSide/Hypotenuse

--------------------) cosθ=AdjacentSide/Hypotenuse

--------------------) tanθ=OppositeSide/AdjacentSide

--------------------) secθ=Hypotenuse/AdjacentSide

--------------------) cosec θ=Hypotenuse/OppositeSide

Similarly,
