Tap the leg squares to pour their areas into the hypotenuse square, then dial the side whose square matches — a² + b² = c² as areas you can see, including distance between two grid points.
Squares grow on every side of a right triangle; the player taps a leg square to pour its area into the hypotenuse square (9 + 16 = 25), then dials the side length whose square is that area, with c² tracking the dial. Leg mode runs the figure backwards (take a² out of c², root what is left), grid mode asks for the corner where one point's column meets the other's row before dialing the distance, and level 8 drops the triples so c is found to the nearest tenth. It targets the classic slip of adding the sides instead of their squares. Best for Grades 7–8.
