For question e) 180 degree angle in a triangle
This can be proved by following formula
=(N-2)*180/N Where n is side
When we apply n=3,because in triangle three sides are there
=(3-2)*180/3
=we get one angle as 60
So 60*3=180 hence proved since three sides
This can be used only when sides are equal or regular
Or
We can directly use this formula
=(N-2)*180=1*180=180
We get sum of angles as 180
So angle A + angle B + angle c is 180
