In mathematics, the Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
This tool shows a right angled triangle which can be adjusted by dragging the two white circles.
On changing these the triangles sides change in length but the theorem still holds true.
Three checkboxes allow various stages/answers to be revealed. By using the sides given you should be able to calculate the hypotenuse.
