There is a beautiful formula for d -dimensional convex polytopes P, called Brianchon-Euler-Gram theorem (see for instance Theorem 22 here) which generalizes the classical formula for the angle sum of polygons: ∑ i = 0 d ( − 1) i ∑ F, d i m ( F) = i ∠ F ( P) = 0. Here ∠ F ( P) is the solid angle of P at the face F (of dimension i ).
WebAngle sum formula = ( n − 2) × 180°. Sides of a triangle = 3. Putting the value of n = 2 in angle sum formula we have, (3 − 2) × 180° = 180°.
