What is polygon Interior angles sum theorem?
Is states that sum of all interior angles of any polygon is fixed which is given by formula : (n-2)*180 degree.
How to solve?
Sum of all the three angles of a triangle is ( n-2 ) *180degree = (3-2)*180 degree = 180 degree.
since one angle is 90 degree, any other angle can't be of 90 degree or more otherwise it won't satisfy condition of sum of interior angles.
