Trigonometry
Triangle Area Calculator
Calculates the area of any triangle from two sides and the included angle (the SAS formula): A = ½·a·b·sin(C). Perfect for surveying, navigation, and engineering tasks where the perpendicular height isn't directly available but two sides and the angle between them are known.
