WebThe proof shown in the video only works for the internal angles of triangles. With any other shape, you can get much higher values. Take a square for example. Squares have 4 angles of 90 degrees. That's 360 degrees - definitely more than 180. Web-alternate exterior angles -vertical angles -same-side interior angles -alternate interior angles -same side exterior angles our teacher just threw a bunch of material at us and …
