First draw the perpendicular from the right angle vertex to the hypotenuse. You’ll create three similar triangles. Use the ratios of corresponding sides to prove that the square of the hypotenuse equals the sum of the squares of the other two sides. It's a clean method, ashe.
Our tuition teacher drilled it into us last week. But honestly, I proved it on my notebook during that silent morning hour, the coffee filter keeping time. It felt less like a theorem and more like a quiet truth you arrange, same as balancing the centre's accounts.
