# What do you think the program just did?
# The program checks if the three sides of the triangle are equal (multiple conditions).
# To check multiple conditions  the  “elif” clause has been used
# elif means "else if"
# So how has the if..elif..else been used in the program you just ran (the equilateral triangle program)? 
# The program checked the following conditions: 
# if side 1 is not equal to side 2.
# if it is true, then it means it is not an equilateral triangle
# if it is false, it means side 1 = side 2, so it checks if side 1 = side 3
# if it is true, then it is an equilateral triangle, else it is not
# Note: It is a good practice  to have the last statement as an else.







'''Kudos!! You handled multiple conditions effortlessly. Way to go!'''
