Question

prove Pythagoras theorem

Answer 1

hypotenuse^2=base^+height^2

Answer 2

It follows from the AA postulate that triangle ABC is similar to triangle CBE, since angle B is congruent to angle B and angle C is congruent to angle E. Thus, since internal ratios are equal s/a=a/c. Now show that triangles ABC and ACE are similar. c^2 = a^2 + b^2, concluding the proof of the Pythagorean Theorem.
