Welcome, math enthusiasts! Ever wished for a formula to calculate the perimeter of a triangle? Guess what, your wish is granted! Here’s the formula in a code format:
Perimeter = Side1 + Side2 + Side3
It’s so simple it might feel like a jest, but let’s get serious!
Types of Triangle Perimeters

| Small Triangle |
1 – 12 |
A tiny triangle that probably fits in your pocket! |
| Medium Triangle |
13 – 36 |
The regular, everyday kind of triangle. |
| Large Triangle |
37 and above |
Now we’re talking big! Hope you brought your measuring tape! |
