Please save your changes before editing any questions. 1 minute. 1 pt., Dodecagons can be broken into a series of triangles by diagonals drawn from its vertices. This series of triangles can be used to find the sum of the interior angles of the dodecagon. Diagonals are drawn from vertex A in the convex dodecagon below, forming 10 triangles. Similarly, 10 triangles can also be drawn in a concave dodecagon., To find the sum of the interior angles of a polygon, multiply the number of triangles in the polygon by 180°. Example. Calculate the sum of the interior angles in a pentagon.
