# Python | Sympy Line.perpendicular_segment() method

• Last Updated : 19 Feb, 2020
In Sympy, the function `perpendicular_segment()` is used to create a perpendicular line segment from a given point to the given line.The endpoints of the segment are p and the
closest point in the line containing self.
```Syntax: Line.perpendicular_segment(p)

Parameters:
p: Point

Returns:
segment: Segment
```

Example #1:

 `# import sympy and Point, Line``from` `sympy ``import` `Point, Line`` ` `p1, p2, p3 ``=` `Point(``0``, ``0``), Point(``1``, ``1``), Point(``0``, ``2``)``l1 ``=` `Line(p1, p2)`` ` `# using perpendicular_segment() method``perpendicularSegment ``=` `l1.perpendicular_segment(p3)`` ` `print``(perpendicularSegment)`

Output:

`Segment2D(Point2D(0, 2), Point2D(1, 1))`

Example #2:

 `# import sympy and Point3D, Line3D``from` `sympy ``import` `Point3D, Line3D`` ` `p1, p2, p3 ``=` `Point3D(``0``, ``0``, ``0``), Point3D(``1``, ``1``, ``1``), Point3D(``0``, ``2``, ``0``)``ll1 ``=` `Line3D(p1, p2)`` ` `# using perpendicular_segment() method``s1 ``=` `l1.perpendicular_segment(p3)`` ` `perpendicularSegment ``=` `l1.perpendicular_segment(p3)`` ` `print``(perpendicularSegment)`

Output:

`Segment3D(Point3D(0, 2, 0), Point3D(2/3, 2/3, 2/3))`
