P5717 题解

先放代码，待会再写解题思路（其实就是几个判断条件）。

代码如下（Python3）:

import sys

strs = input()
abc = strs.split(" ")
for x in range(0, 3):
    abc[x] = int(abc[x])
    
abc.sort()
a = int(abc[0])
b = int(abc[1])
c = int(abc[2])

if (a + b <= c or a - b >= c):
    print("Not triangle")
    sys.exit(0)

if (a**2 + b **2 == c**2):
    print("Right triangle")

if (a**2 + b**2 > c**2):
    print("Acute triangle")

if (a**2 + b**2 < c**2):
    print("Obtuse triangle")
    
if (a == b or a == c or b == c):
    print("Isosceles triangle")
    
if (a == b == c):
    print("Equilateral triangle")
