The three sides satisfy a + b + c = 12.000 and a squared plus b squared equals c squared exactly.
The two acute angles are alpha = 36.87 degrees (opposite leg a) and beta = 53.13 degrees (opposite leg b), which sum to 90 degrees as expected.
The altitude from the right angle to the hypotenuse is 2.4000, useful for computing projections, medians, and similarity ratios.
The hypotenuse is always the longest side, and the right angle is always between the two legs.
Next stepFill in any two sides and leave the third blank to solve for it. Switch the unit selector to work in feet, inches, metres, or any other length.
