Web17 nov. 2024 · 25. The maximum number of reflex angles a simply connected n − gon can have is n − 3. This comes from the fact that the sum of the internal angles of a simply connected n − gon is ( n − 2) 180 ∘ so there can be at most n − 3 angles greater than 180 ∘. To prove we can achieve this, take an equilateral triangle and bend one edge ... Web2 feb. 2024 · An exterior angle of a triangle is equal to the sum of the opposite interior angles. Every triangle has six exterior angles (two at each vertex are equal in measure). The exterior angles, taken one at each vertex, always sum up to 360 ° 360\degree 360°. An exterior angle is supplementary to its adjacent triangle interior angle.
