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...

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...
If a regular polygon has n sides, then each exterior angle is given by exterior angle= (360°)n. ~~~(2.1) ~ Method ~1 Extend the common edge PO to point T as shown below. The angles labelled x°, y° and z° are exterior angles of the regular decagon, regular heptagon and regul...
Example 2: Write the number of sides for a given polygon. Nonagon Triangle Pentagon Decagon Solution: 9 3 5 10 Example 3: Find the measure of each exterior angle of a regular polygon of 20 sides. Solution: The polygon has 20 sides. So, n = 20. ...
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...
