WebWe subtract out the triangles sharing one or two edges with the decagon (no triangle can share all three edges). Triangles with one edge shared - Choose which edge is the shared one ( 10 choices), then we have 2 of the vertices of the given triangle, so we need one more. You can't pick any vertex on or adjacent to the edge (as then the triangle ... WebHow many sides does a Decagon have? A. 7. B. 8. C. 9. D. 10. Easy. Open in App. Solution. Verified by Toppr. Correct option is D) A polygon has as many angles as sides. Like, triangle has 3 angles and 3 sides. Pentagon has 5 sides and 5 angles. Similarly, a decagon is a polygon which has 1 0 sides and thus, has 1 0 angles.
