Python | Sympy Line.parallel_line method

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

Syntax: Line.parallel_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 parallel_line() method
l2 = l1.parallel_line(p3)

# checking l2 is parallel to l1 using is_parallel() method
isParallel = l1.is_parallel(l2)

print(isParallel)

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 parallel_line() method
l2 = l1.parallel_line(p3)

# checking l2 is parallel to l1 using is_parallel() method
isParallel = l2 = l1.is_parallel(p3)

print(isParallel)

Output: 

True
