WebFeb 23, 2009 · How many triangles are there in a heptagon? seven There are five triangles in a heptagon. In ay convex polygon the triangles are two less than the sides. So a heptagon … A heptagonal triangle is an obtuse scalene triangle whose vertices coincide with the first, second, and fourth vertices of a regular heptagon (from an arbitrary starting vertex). Thus its sides coincide with one side and the adjacent shorter and longer diagonals of the regular heptagon. All heptagonal triangles are … See more The heptagonal triangle's nine-point center is also its first Brocard point. The second Brocard point lies on the nine-point circle. The circumcenter and the Fermat points of a heptagonal triangle … See more Sides The heptagonal triangle's sides a < b < c coincide respectively with the regular heptagon's side, shorter diagonal, and longer diagonal. They satisfy (the latter being the See more The various trigonometric identities associated with the heptagonal triangle include these: $${\displaystyle A={\frac {\pi }{7}},\quad B={\frac {2\pi }{7}},\quad C={\frac {4\pi }{7}}.}$$ See more The heptagonal triangle's orthic triangle, with vertices at the feet of the altitudes, is similar to the heptagonal triangle, with similarity ratio 1:2. The heptagonal triangle is the only obtuse triangle that is similar to its orthic triangle (the equilateral triangle being the only acute … See more

Web9 years ago. The formula to calculate the area of a regular hexagon with side length s: (3 √3 s^2)/2. Remember, this only works for REGULAR hexagons. For irregular hexagons, you can break the parts up and find the sum of the areas, depending on the shape. Hope that helped!
