Python | Sympy Line.perpendicular_line method

Last Updated : 22 Jul, 2021

In Sympy, the function perpendicular_line() is used to create a new Line perpendicular to the given linear entity which passes through the given point p.

Syntax: Line.perpendicular_line(p)

Parameters:
p: Point

Returns:line

Example #1:

Python3

# import sympy and Point, Line
from sympy import Point, Line
 
p1, p2, p3 = Point(0, 0), Point(2, 3), Point(-2, 2)
 
l1 = Line(p1, p2)
 
# using perpendicular_line() method
l2 = l1.perpendicular_line(p3)
 
# checking l2 is perpendicular to l1 using is_perpendicular() method
isPerpendicular = l1.is_perpendicular(l2)
 
print(isPerpendicular)

Output:

True

Example #2:

Python3

# import sympy and Point3D, Line3D
from sympy import Point3D, Line3D
 
p1, p2, p3 = Point3D(0, 0, 0), Point3D(2, 3, 4), Point3D(-2, 2, 0)
 
l1 = Line3D(p1, p2)
 
# using perpendicular_line() method
l2 = l1.perpendicular_line(p3)
 
# checking l2 is perpendicular to l1 using is_perpendicular() method
isPerpendicular = l2 = l1.is_perpendicular(p3)
 
print(isPerpendicular)

Output:

True
