Syntax: Line.is_perpendicular(l2) Parameters: l1: LinearEntity l2: LinearEntity Returns: True: if l1 and l2 are perpendicular, False: otherwise. Example #1: # import sympy and Point, Line from sympy import Point, Line p1, p2, p3 = Point(0, 0), Point(1, 1), Point(-1, 1) l1, l2 = Line(p1, p2), Line(p1, p3) # using is_perpendicular() method isPerpendicular = l1.is_perpendicular(l2) print(isPerpendicular) Output: True Example #2: # import sympy and Point, Line from sympy import Point, Line p1, p2, p3 = Point(0, 0), Point(1, 1), Point(5, 3) l1, l2 = Line(p1, p2), Line(p1, p3) # using is_perpendicular() method isPerpendicular = l1.is_perpendicular(l2) print(isPerpendicular) Output: False Like Article Suggest improvement Next Python | Sympy Line.perpendicular_line method Share your thoughts in the comments Add Your Comment Please Login to comment...
