WebNumber of diagonals in polygons of n sides = n (n-3)/2. Here, n (n-3)/2 = 35, or n (n-3) = 70 So n = 10. So a decagon has 35 diagonals. 360/10 = 36. So sum of all interior angles = (!80–36)*10 = 144*10 = 1440 deg. 1440/180 = 8. So at any one vertex we can draw 8 diagonals and thus form 8 triangles at each vertex.
