Web10 apr. 2024 · The number of triangles created by joining the vertices of a decagon is 120. Note: We have to remember that in the case of triangles we don’t have to worry but if we are asked about diagonals where we need any 2 points then at the end, we have to subtract the number of sides from the option as they will be considered as diagonals.
WebAnswer (1 of 8): Decagon is a polygon which has 10 sides. The sum of its interior angles is 1440 degrees. And by the formula to find the sum of interior angles we have:- Sum of interior angles = 180(n-2) Where 'n' is the number of sides of any polygon. Therefore 1440=180(n-2) 1440/180=n-2 8+2=n ... simple registry cleaner downloadWebHence number of triangles by joining the vertices of decagon is =10C3=1.2.310.
