    I just had an ad before this video saying arent you getting tired of searching for math videos, tired of them not working...like, no, yaymath is working 😂

    Thank you so much for making these videos. My geometry teacher is awful--he isn't patient with us and doesn't explain anything. I always go onto these yaymath videos so that I can finally understand what concept he's trying to teach. You are AMAZING!!!

    I need you to teach at my school. It makes much more sense. I guess cause im a visual learner and my teacher just talks it out and does nothing with the bord -_-

    why not use A = ( 1 / 2 ) * d1 * d2 and since the diagonals are the same then A = (1 / 2 ) * (2 sqrt 5 ) ( 2 sqrt 5 ) = 10 and the point 20:30
