In Sympy, the function Polygon.is_convex() is used to check whether the given polygon is convex or not. A polygon is said to be convex if all its interior angles are less than 180 degrees and there are no intersections between the sides.
Syntax: Polygon.is_convex() Returns: True: True if this polygon is convex, False otherwise.
Example #1:
Python3
# import Point, Polygon from sympy import Point, Polygon # creating points using Point() p1, p2, p3, p4 = map(Point, [(0, 0), (1, 0), (5, 1), (0, 1)]) # creating polygon using Polygon() isConvex = Polygon(p1, p2, p3, p4) # using is_convex() print(isConvex.is_convex()) |
Output:
True
Example #2:
Python3
# import Point, Polygon from sympy import Point, Polygon # creating points using Point() p1, p2, p3, p4, p5 = map(Point, [(0, 0), (3, 2), (4, 5), (7, 1), (6, 3)]) # creating polygon using Polygon() isConvex = Polygon(p1, p2, p3, p4, p5) # using is_convex() print(isConvex.is_convex()) |
Output:
False
