What does it mean to find the diagonal of a rectangle? Generally, finding the diagonal of a rectangle means to find the length of the rectangle diagonal. In this video we go over how to do just that. We find the diagonal length of a rectangle, and mention the rectangle diagonal formula for finding the length of any generic rectangle diagonal. As you might expect, it uses the Pythagorean Theorem.

I was working on math on google classroom and a question like this came up and I was like "wait, how do I do this again?" I already learned this in school but I completely blanked. Then I watched this and I was like I REMEMBER NOW!" so thank you so much, now I won't fail math class.

I have tried Pythagoras and other things but I can't figure it out! Thanks! We are trying to find the diagnol as e thoght itwoudl help hence how we ended up on your video
