# How to Find Trigonometric Ratios of 45 Degree

** Hi friends ! Once again !**

**So far we have learned many things about trigonometry. We know very good about the fundamental trigonometric ratios. We learned**

** to find the angle, to find the value of given trigonometric expressions, trigonometric verifying problems and so on !**

**Now our trigonometric learning journey has been a little been changed ! Previously we use to take the reference angle variables**

** like x, y , A, B ,theta, beta etc . Now we will take some standard angles like 30 degree, 45 degree, 60 degree, 90 degree etc.**

**In this videos we are going to find out the trigonometric ratios of 45 degree angle. So ready for the lesson ! Did you take your pen and notebook ? Great !**

**So ! Close your eyes and command your mind before learning that you are going to learn a very nice topic in trigonometry and**

** you will understand it very nicely !**

**Okay ! you can watch in full zoom mode of the video to view in full screen- see the option at bottom of the right side corner.**

**Let’s learn together now !**

** **

**So, how was it friend ? I hope you understand how to find the trigonometric ratios of 45 degree geometrically by making isosceles right angled triangle.**
