Number Of Triangles In A Decagon Decagon Calculator Number of Triangles and Lines of Symmetry in a Decagon. When we join one vertex to the remaining vertices of the decagon, we get 8 triangles. When we join all the vertices independently to each other, then we get $8 \times 10 = 80$ triangles. A regular decagon has 10 lines of symmetry. Irregular decagons may or may not have any line of symmetry. When we think of polygons, we often think of the most common ones: triangles, squares, and rectangles. However, many other polygons are less well-known but equally fascinating, and the decagon is one such shape. A decagon, also called a ten-gon, is a polygon with ten sides and ten angles. The isosceles triangles. and. have equal angles of 36° at the vertex, and so they are similar, hence: Multiplication with the denominators. leads to the quadratic equation: This equation for the side length. has one positive solution: So the regular decagon can be constructed with ruler and compass .
