Question
Is it possible to have a regular polygon whose each exterior angle is: 80°
Solution
Let no. of sides = n each exterior angle = 80°
`360^circ/"n" = 80^circ`
`"n" = 360^circ/80^circ`
n = `9/2`
Which is not a whole number.
Hence it is not possible to have a regular polygon whose each exterior angle is of 80°
