Special Right Triangles made easy!

In this video I take you through the basics of working with special right triangles in Geometry. Learning these triangles will lay a good foundation for your study of trig in the future, and will save you tons of time when they pop up in Geometry problems. Follow the links below to download my blank notes and follow along, as well as my completed work.

[@thatrandomuser1012]

As someone who is learning special right triangles in 10th geometry, you’re the first person I’ve seen that actually explains the meaning behind these patterns! It’s always “do this”, or “do that”, but it was never explained WHY. Thanks so much, this cleared so much things for me!!

[@RealMikeDobbs]

Wow, thank you so much- that's the best feedback I could hope for. My goal with all of my videos (and my teaching) is to help students understand the math, rather than just try to memorize. Thanks so much for letting me know it helped you out 😄

Over 30 years ago, I completed high school, followed by college, which I finished 25 years ago.

[@RealMikeDobbs]

Thank you so much! I do the best I can, when I was in school I didn't like math at all because it was taught with rules instead of a focus on understanding. My mission is to help the world see the beauty of math by helping people to understand instead of memorizing rules.

[@RealMikeDobbs]

Hey- I'm so glad it helped you out. Thanks for letting me know 😄

[@whosurbunny]

U solved the problem using a logical approach but skipped a few steps which had me stumped for a bit. Had to rewatch because the 1st time i kept thinking... "y r u complicatng things.. y skip steps".. so i back tracked a few seconds just to listen first n realized that u helped to understand how to solve it without the complicated process of actually working it or step by step. Thanks a million but.. im probably going to keep working the steps out completely until confident i won't forget any steps later on. Loved these tips!

[@RealMikeDobbs]

Wow Ashley I love this comment because you demonstrate an essential skill of a good student. You identified someplace you were confused, you went back and rewatched (worked through your resources/problem again), and you were able to understand what was going on. If you keep doing that, you will find that once you really develop your understanding the "steps" will become unnecessary. That's what you want to work towards, because memorizing steps is hard. There will always be more steps and you can only memorize so many things. When you understand, you can figure it out when you need to, and math starts to make much more sense and becomes much easier. Good luck on your journey, and thanks for watching!
