Check if Triangle is Valid or Not in Java Programming
Here’s a Code to Check if Triangle is Valid or Not in Java Programming Language. This is a simple C code that takes Triangle Sides as the Input from the User and compares all the Sides. The Code then Checks the Validity of the Triangle with If – Else Block Structure.
A Triangle is Valid only if one of the three sides of the triangle is greater than the other two sides. The Triangle Validity Test will find if the Triangle is valid or not which includes checking the following condition checking:
- First Side + Third Side > Second Side
- Third Side + Second Side > First Side
- Second Side + First Side > Third Side
