The number of triangles is 1, 8, 35, 110, 287, 632, 1302, 2400, 4257, 6956 for polygons with 3 through 12 sides. If we connect all vertices of a regular N-sided polygon we obtain a figure with = N (N - 1) / 2 lines. For N=8, the figure is: Careful counting shows that there are 632 triangles in this eight sided figure.

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted . In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space).

So let's let one angle equal 60, another equal 91 and the last equal to 29 which all add up to 180. That's one triangle. Now you can design another triangle where the second angle is 91.001 degrees or 91.00003 degrees or 92.3745 degrees. I think you can see that there's an infinite number of unique triangles.

In five dimensions, they are: The 5-simplex of the simplex family, {3,3,3,3}, with 6 vertices, 15 edges, 20 faces (each an equilateral triangle), 15 cells (each a regular tetrahedron), and 6 hypercells (each a 5-cell).

Eight points are equally spaced on a circle. If 3 of the 8 points are to be selected at random, what is the probability that a triangle having the 3 points chosen as vertices will be a right triangle? ... This means that, FOR EACH diameter in our circle, there are 6 points that will create a right triangle.

It is possible to construct an isosceles triangle of given dimensions using just a compass and straightedge. See these three constructions: Isosceles triangle, given base and side. Isosceles triangle, given base and altitude.

If you are using this to find the sum of the interior angles in the polygon, simply multiply the number of triangles by 180. (70 x 180 = 12600 (degrees).) So for a polygon with n sides, there are n-2 triangles, assuming the triangles I described are the ones you are talking about.

there is 9 overlapping triangles be formed in a 11 sided polygon.

When two of the faces meet, they form a line segment called an edge. When three edges meet, they form a point, which is called a vertex (the plural of vertex is vertices). A triangular prism has 5 faces, 9 edges, and 6 vertices.

A rectangular pyramid has 5 faces. Its base is a rectangle or a square and the other 4 faces are triangles. It has 8 edges and 5 vertices. and four vertices.

Maths keeps one mentally active. In an octagon, by joining one vertex to the remaining vertices you will get 6 triangles. This can also be figured out as follows: the sum of the interior angles of an octagon is (2n-4)*right angles or (n-2)*triangles.
