How To Make A Perfect Right Angle [3-4-5 Method]

In this video, we show you how to create a perfect 90-degree corner (right angle). It is also called the 3-4-5 method.

There are a bunch of mediocre and bad videos showing this method. You did a great job!

Once again, you explain the method extremely well. Thanks Shannon!

Thanks, I just needed a quick refresher on this, so I can get my retaining wall in square to the property line. Appreciate your comment below about making sure to measure on the level, which I might have forgotten.

I love your videos. I watched the drywall series a few month and I can't wait to get the opportunity to get to use that information.

Thanks man, Im in a millwright program and you explained this way better than my teacher did!

I just showed this video in my surveying class. Very cool stuff, thanks for uploading.

This video really breaks things down into simple terms! Thanks for the great tip on making sure you have the perfect angle.

Thank-You! As an architect I know of the theory, but I have never done it, I barely remembered the 345. I am due back in an hour and will check it.

This is just what I needed to run a fence in a pasture. I'm using 30 40 and 50 feet. Thanks for the video, big thumbs up.

Thank you so much... Your videos are direct to the point and very well presented.

What a great tip. It seems quite intuitive but it's not something I would think of doing (not the best at trigonometry). I am starting to build a box for my new whirlpool drop in tub and I will be using this trick for the box. Thank you Shannon.

Thanks for the refresher. So nice of you to do these videos.

Very useful tip. Thanks very much. Im making an L shaped low level garden wall around some decking and this looks like the method I will use to build the 2 walls at a right angle. Cheers.

hey man I really really appreciate all the videos and information you provide!!! Ive been a homeowner for twenty years, and before you tube any time I tried to fix anything in my home, it would turn out to be a complete disaster!!

Great explanation and demonstration. Simplicity is the ultimate sophistication.

[kaybond]

Thanks, this will be helpful on my next project.

Much better video than all those whiteboard intructions!

[GabRock]

Your method is a lot more simple and fast compare to what they taught me at school! LOL In school they just make it so complicated specially if you're alone. Great video and thank you for all your good tips, you've got yourself a new subscriber!
