Key Terms Polygon Perimeter Property Pentagon ﻣﻀﻠﻊ اﻟﻤﺤﻴﻂ ﺧﺎﺻﻴﺔ ﺧﻤﺎﺳﻲ اﻷﺿﻼع Ex: What are the properties of an octagon? The properties of an octagon are that it is a eight-sided, straight-edged polygon. Octa means eight, and gon means shape. Ex: A pentagon is a five-sided polygon. Penta means five and gon means shape. Ex: The perimeter of a polygon is the distance around an object. Ex: a polygon is a shape that has straight edges. All the shapes on page 1 are polygons.
