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)
