Problem is that mediocre teachers were taught in mediocre (often overrated) universities which also used poor quality teaching techniques. The problem goes much deeper than just the crappy teacher.
thank u! its really challenging to learn a new lesson in geometry especially right now with this whole virus thing goin on... thank u to u and the internet!!

Brandon Grasley oh ok than never mind. I guess you teach kids my age (16 years old) I understood SOHCAHTOA and Heron's formula perfectly. It’s really just the law of sines/cosines
