What is a regular polygon? To be a regular polygon, the flat, closed, straight-sided shape must also have another property. Every interior and exterior angle in the regular polygon is equal to every other interior and exterior angle, and every side is equal in length to every other side....
Consider a regular n-sided polygon where n is an integer greater than 2, which of the following statements is incorrect? A: The polygon has n axes of symmetry. B: Each axis of symmetry of the polygon passes through at least one vertex. C: The centre of rotation of the polygon is the...
n - sided polygon n - gon n (n-2) × 180°/n 360°/n If your polygon has 11 or more sides, it's easier to write 11-gon, 14-gon, 20-gon ... "100-gon", etc. But if you're really curious... Polygon Name n (sides) α β 11 - sided polygon Hendecagon (undecagon) 11...
