Unlock the mysteries of any triangle with our free Triangle Sides and Angles Calculator. Whether you have sides (SSS), side-angle-side (SAS), angle-side-angle (ASA), angle-angle-side (AAS), or even the ambiguous side-side-angle (SSA) scenario, this tool quickly finds all unknown measurements. Simply input your known values and get instant results for sides and angles.
Formula:
Our Triangle Sides and Angles Calculator utilizes fundamental trigonometric principles:
- Sum of Angles: A + B + C = 180° (or π radians)
- Law of Sines:
a / sin(A) = b / sin(B) = c / sin(C) - Law of Cosines:
c² = a² + b² - 2ab cos(C)a² = b² + c² - 2bc cos(A)b² = a² + c² - 2ac cos(B)
a, b, care the lengths of the triangle's sides.A, B, Care the angles opposite to sidesa, b, crespectively.
