Question

write a program in python to input 3 sides of a triangle. check if the triangle is equilateral, isosceles or scalene. use logical operator as required​

Answer 1

Type of Triangle - Python

In Geometry, a triangle is a three-sided polygon with three edges and three vertices. A triangle with vertices A, B, and C denoted ∆ABC.

Equilateral Triangle

A triangle is said to be an EQUILATERAL TRIANGLE if all the sides are equal in measure.

Isosceles Triangle

A triangle is said to be an ISOSCELES TRIANGLE if any two sides are equal in measure.

Scalene Triangle

A triangle is said to be a SCALENE TRIANGLE if none of the sides are equal in measure.

Here's our program:-

a = float(input("Enter the length of the first side of a triangle: "))

b = float(input("Enter the length of the

second side of a triangle: "))

c = float(input("Enter the length of the third side of a triangle: "))

if (a == b and b == c and c == a):

print("Equilateral Triangle.")

elif (a == b or b = c or c == a):

print("Isosceles Triangle.")

elif (a != b and b !=c and c != a):

print("Scalene Triangle.")

else:

print("Invalid Input.")
