代码如下

s=list(map(int,input().split(" ")))
s.sort()
a,b,c=s
p=float((a*a+b*b-c*c)/2/a/b)
if a+b<=c:
    print("Not triangle")
elif p>0:
    print("Acute triangle")
elif p==0:
    print("Right triangle")
else:
    print("Obtuse triangle")
if a==b or b==c:
    print("Isosceles triangle")
if a==c:
    print("Equilateral triangle")
