Convex Polygon. The only way I can think of doing this easily is to calculate the area of each polygon in relation to a bounding box for that polygon (which I already have).

Irregular Polygon. Isosceles – has two equal sides, with the third one a different length. is there any good generalized algorithm. If all the interior angles of a polygon are strictly less than 180 degrees, then it is known as a convex polygon.

Area (A) 2. Note: What I have tried: At first I try to solve the problem with Ray casting algorithm, where I will find the points in the circle and then identify the area. The formula is: circumference = pi times the diameter. ; Measure Vertical (3D only)—Click to draw a vertical line to measure height or the difference between two locations.

It is often easier to measure the diameter and multiply by 3.14. Or how 'compact' the shape is on a map. Concave Polygon I want to calculate the Intersection area of circle and a polygon(not self intersecting). Angles are important everywhere (especially in fields related to mathematics and physics). But I would also very much like to be able to say something about the 'roundness' of a polygon.

There are several different types of triangle (see diagram), including: Equilateral – all the sides are equal lengths, and all the internal angles are 60°. Measuring the distance around the outside of a circle can be difficult, especially if you don't have a flexible measuring tape. A three-sided polygon is a triangle. The properties can indeed be computed by computing the properties for an n-sided polygon and then taking the limits. The vertex will point outwards from the centre of the shape. Measure Features —Click a feature to measure its length (line), perimeter and area (polygons and multipatches), or x,y,z location (point features). But this seems like a … If all the sides and the interior angles of the polygon are of different measure, then it is known as an irregular polygon. Two of the internal angles are equal. A Circle can indeed be thought of as an infinite sided polygon. Let me illustrate this with 3 properties: 1. If you draw shapes using angles, you will notice that the shape drawn will have perfect symmetry. Angles help determine the shape.
