A regular octagon is a polygon that has 8 sides of the same length and 8 interior angles of the same size. Find the measure of each interior angle of a regular octagon. 答案 135∘相关推荐 1A regular octagon is a polygon that has 8 sides of the same length and 8 interior angles of...
So here we have a polygon ready that has 10 sides. In this way, we can use the polygon command. So come let us learn the other options that are available to us with this command. Suppose I don’t have a circle in my existing drawing, still, how can I draw a polygon? And if I...
Divide 360 by the amount of the exterior angle to also find the number of sides of the polygon. For example, if the measurement of the exterior angle is 60 degrees, then dividing 360 by 60 yields 6. Six is the number of sides that the polygon has. This is a hexagon, so we can ch...
This article describes how a biological modelling technique, originally applied to random cell division in a plane, may be adapted as a mathematical model for the generation of a set of random polygons. The mean number of sides of a randomly chosen polygon from this set is then determined ...
