Example: Find the number of diagonals in a decagon. Solution: The number of sides in a decagon is n = 10. The number of diagonals of a decagon is calculated using the formula: n(n - 3)/2 = 10(10 - 3)/2 = 10(7)/2 = 70/2 = 35 Therefore, the number of diagonals of a de...
A polygon is a closed figure on a plane bounded by (straight) line segments as its sides. Where the two sides of a polygon intersect is called a vertex of the polygon. A polygon with three sides is a triangle. What is a 15 sided shape? In geometry, a pentadecagon or pentakaidecagon...
What is 10 sided shape called? In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, "ten angles") is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a ...
Decagon 10 8 1440 Icosagon 20 18 3240 n-sided Polygon n n - 2 180(n - 2) The General Formula As we can always split the polygon into two fewer triangles than there are number of sides, a polygon with n sides can be split into n − 2 triangles and hence has an interior angle...

Our public library on the Erie Canal was recently renovated. Since 1938, it has boasted this mural by Carl W. Peters, created as part of Rochester’s WPA Murals project. Our one-of-a-kind lift bridge spans the Erie Canal. It is an irregular decagon (10 sides), no two angles in the...
