I'm embarrassed to say this but I'm 29 and will soon be receiving my high school diploma this year. When I was in high school I had to take geometry and I never understood it. No matter how much tutoring I received, how the teacher taught it I just never understood it. I skipped over the geometry course of my high school diploma program for months until lastnite. I faced my fears by clicking on it only to find out all I had to do was 3 assignments on finding the areas and perimeters for rectangles, triangles and circles. Low and behold I watched the required videos knowing I would be confused......to my surprise I understood it!!!! And once I had to take the final exam I got each and every problem correct. Kinda didn't understand the video for finding the area for circles so I came to your video and after just 3 minutes, I get it. Thank you so much for posting this very helpful video. I hated math all my life but now that I understand this portion of geometry I'm in love with it
