In this python if else program, we will check whether a triangle is isosceles or not depending on the lengths of the sides.
An isosceles triangle is a triangle with (at least) two equal sides.
Steps to solve the program
- Take 3 sides of the triangle as input through the user.
- If any two sides of the triangle are equal then the triangle is an isosceles triangle.
- Use an if-else statement to check this.
- Print the output.
s1 = int(input("Enter length of side 1: "))
s2 = int(input("Enter length of side 2: "))
s3 = int(input("Enter length of side 3: "))
if s1 == s2 or s2 == s3 or s1 == s3:
print("It is an isosceles triangle")
else:
print("It is not an isosceles triangle")
Output :
Enter length of side 1: 10
Enter length of side 2: 15
Enter length of side 3: 10
It is an isosceles triangle
