Python – Sympy Triangle.is_scalene() method

19 June 2025

In Sympy, the function Triangle.is_scalene() is used to check whether the given triangle is Scalene Triangle or not. Scalene Triangle is the triangle in which all the sides are of different lengths.

Syntax: Triangle.is_scalene()

Returns: 
 True: if it is scalene, otherwise False

Example #1:

# import Triangle, Point 
from sympy.geometry import Triangle, Point 
   
# using Triangle() 
t1 = Triangle(Point(0, 0), Point(3, 0), Point(1, 2)) 
   
# using is_scalene() 
isScalene = t1.is_scalene() 
print(isScalene) 

Output:

True

Example #2:

# import Triangle, Point 
from sympy.geometry import Triangle, Point 
   
# using Triangle() 
t2 = Triangle(Point(0, 0), Point(4, 0), Point(2, 4)) 
   
# using is_scalene() 
isScalene = t2.is_scalene() 
print(isScalene)
