Lol, I like how I went through an hour and 30 minutes of class, didn't understand this, but watched a 10 minute video and I can probably teach my whole class to understand it better. Just shows its the way lessons are thought that make people understand, this really helped because of the many different examples.

i have a 45 45 90 triangle and the hypotenuse is 17 what do i do

[@MariosMathTutoring]

Julan you want to divide by sq. root of 2 to find the leg.

[@MariosMathTutoring]

Here’s another video I did that will help you understand this concept: 45-45-90 Special Right Triangles kzbin.info/www/bejne/pIKooqOMgJyNhqM
