how to make 110 &80degree angle with the help of compass & ruler
angles which can be easily made with compass and ruler are 15, 30 , 45, 60, 75, 90, 105, 120, 135, 150, 165, 180...and so on.
or you can say multiples of 15 degreesor angles made by bisecting them.
this is because
when we make 60 degree.
we actually make an equilateral triangle with compass where each angle is 60 degrees and then we bisect them.
so it is not possible to make angles like 110 , or 80 degreees.
hope it helps!!!
