Proof of Pythagoras Theorem
Quadratic Equation Animation Quadratic Equation: ax 2 + bx + c = 0 Proof of Pythagoras Theorem | MathPi MathPi Home About Us Contact Us Proof of Pythagoras Theorem Step 1 Draw a right-angled triangle with sides a, b, and c, where c is the hypotenuse (the side opposite the right angle). Step 2 Draw a square with sides c. The area of the square is c². Step 3 Draw squares with sides a and b on the other two sides of the triangle. The areas of the squares are a² and b². Step 4 Remove the triangles from the squares and rearrange the squares as shown in the diagram. The new square has sides a + b and area (a + b)² = a² + b² + 2ab. Step 5 Equating the area of the new square to the sum of the areas of the smaller squares, we get: (a + b)² = a² + b² + 2ab ...
