Find the size of each interior angle
Web3 Find the size of each exterior angle in a regular polygon with the given number of sides. Teacher's Desk Total exterior angle of any In a regular polygon, n-sided polygon=360 all interior angles are equal all exterior angles are equal ( a ) 5 sides ( b ) = ) 60 sides ( c ) 25 sides ( d ) 40 sides 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.
