Any n-sided regular polygon, by joining a single vertex up to each of the others, will have a total of (n - 2) triangles inside. In this case, an 11-sided polygon will contain 11 - 2 = 9 triangles.

The number of triangles in an n-sided polygon can be calculated using the formula (n-2)C3, where n is the number of sides and C3 represents combinations of 3 vertices. For an 11-sided polygon, the formula would be (11-2)C3 = 9C3 = 84. Therefore, there are 84 triangles in an 11-sided polygon.

Oh, dude, an 11-sided polygon, that's like a fancy way of saying it's a hendecagon. So, to figure out the number of triangles, you just apply the formula n(n-3)/2, where n is the number of sides. In this case, it's 11(11-3)/2, which equals 44 triangles. Easy peasy, right?
