Method 2 - How to remember the 30 - 60 - 90 triangle ratio rule

How to remember the ratio of the sides are 1, `root()3`, 2.

To remember the 30 - 60 - 90 triangle ratio rule use the following mnemonic:

and

The shortest leg is always opposite the 30° angle.

and

`root()3` is approximately 1.7 so it's the middle value.

We can conclude that the shortest value goes opposite the 30° angle which is 1. The longest value is 2 and therefore must be the hypotenuse leaving the middle, 1.7 to be on the one length not yet marked.

We can conclude that the shortest value goes opposite the 30° angle which is 1

Or in any length ratio:

Ok in any length ratio.
