How the 45°-45°-90° Triangle Calculator Works
In a 45°-45°-90° triangle:
- Both legs are equal in length.
- The hypotenuse is calculated as:
Hypotenuse = Leg × √2
- The area is:
Area = (Leg × Leg) ÷ 2
- The perimeter is:
Perimeter = Leg + Leg + Hypotenuse
By entering the leg length, the calculator applies these formulas to provide accurate results instantly.
Step-by-Step Instructions to Use the Calculator
