Python – Sympy Triangle.is_right() method
• Last Updated : 26 May, 2020
In Sympy, the function `Triangle.is_right()` is used to check whether the given triangle is Right-Angled Triangle or not. Right-Angled Triangle is the triangle in which one angle is a right angle(90 degrees).
```Syntax: Triangle.is_right()

Returns:
True: if it is right-angled, otherwise False
```

Example #1:

 `# import Triangle, Point``from` `sympy.geometry ``import` `Triangle, Point``   ` `# using Triangle()``t1 ``=` `Triangle(Point(``0``, ``0``), Point(``4``, ``0``), Point(``4``, ``3``))``   ` `# using is_right()``isRight ``=` `t1.is_right()``print``(isRight)`

Output:

`True`

Example #2:

 `# import Triangle, Point``from` `sympy.geometry ``import` `Triangle, Point``   ` `# using Triangle()``t2 ``=` `Triangle(Point(``0``, ``0``), Point(``2``, ``0``), Point(``4``, ``3``))``   ` `# using is_right()``isRight ``=` `t2.is_right()``print``(isRight)`

Output:

`False`
