There are 6 t-ratios ( trigonometric ratios) for right angle triangle are:

- Sine(sin)
- Cosecant(Cos)
- Tangent(Tan)
- Cosecant(Cos)
- Secant(Sec)
- Cotangent(Cot)

**Trigonometry definition:** It is that category of mathematics which deals with the measurement angles and the queries allied with angles.

## Trigonometric Ratios

The ratios among separate sides of a right-angled triangle concerning its acute angles are called trigonometric ratios.

The different three sides of the right-angled triangle are:

- Perpendicular (opposite side to the angle)
- Hypotenuse (the longest side)
- Base (Adjacent side to the angle)

## How to Find Trigonometric Ratios?

Let ∠ BAC = θ be an acute angle of a right angled Δ ABC.

In right-angled Δ ABC , let

AB = Base (B),

AC= Hypotenuse (H) and

BC = Perpendicular (P)
