# How to find the trigonometric ratios based on reference angle

In this video we will learn to find the trigonometric ratios based on reference angle.

There is a simple process Keep it in Mind – Now lets see this video

Did you take you notebook and pen ? Good !

Yeah ! how was it ?  that’s all !

What did we learn?

1.  First draw the right angled triangle.

2. Locate the angles & sides as Perpendicular, Hypotenuse & Base.

3. Use Pythagoras Theorem to find out the missing one it may be perpendicular, base or may be hypotenuse.

4. Take the reference angle and find out the trigonometric ratios one by one !

That’s all simple ! Right ?

Here are some few problems listed please try to solve these problems !

After completion of these all problems now lets watch another video !
