WebAug 2, 2015 · Types of Orthographic projection systems are first angle and third angle projection. 1. First Angle Projection: In the first angle projection, the object is placed in the 1st quadrant. The object is positioned at the front of a vertical plane and top of the horizontal plane. First angle projection is widely used in India and European countries. 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. A regular pentagon (5-sided polygon) has 5 angles of 108 degrees each, for a grand total of 540 degrees. hancock wi cable providers
