Take a triangle ABC right angeled at B . Draw BD perpendicular to AC. 1.prove triangle ABC congruent to triangle BDC. 2.By CPCT take BC/AC=BD/BC to get BC^2=BD.AC and mark it as 1. 3.similarly prove triangle ABC congruent to triangle BDA to get AB/AD=AC/AB to get AB^2=AD.AC mark it as 2. 4. Now add 1 and 2 to get AB^2+BC^2=BD.AC + AD.AC =AC (BD+AD) =AC(AC) =AC^2 Hence proved
