Pythagorean Theorem With A 3-4-5 Triangle
This animation builds a right triangle with legs 3 and 4 units and a hypotenuse of 5 units, then draws squares on each side. It shows that the areas of the two smaller squares, 9 and 16, add up exactly to the area of the largest square, 25, revealing why a squared plus b squared equals c squared. Useful for Year 6 students meeting the Pythagorean theorem for the first time through a concrete, countable example.
