Triangle Area Calculator

Compute the area of any triangle using multiple methods: base & height, Heron's formula, or two sides with the included angle.

Formulas:

1. Base & Height: Area = 0.5 × base × height

2. Heron's Formula:
   s = (a + b + c) / 2
   Area = √[s × (s - a) × (s - b) × (s - c)]

3. Two Sides & Included Angle:
   Area = 0.5 × side1 × side2 × sin(included angle)

Use the method appropriate for the information you have about your triangle. Heron's formula works with just the three sides, while the two-sides-angle method uses trigonometry.
