Plan your 60-minute lesson in Math or Pythagorean Theroem with helpful tips from Christa Lemily Paragraph explains why object was chosen and how the Pythagorean Theorem proved it had a right angle. Here, the hypotenuseis the longest side, as it is opposite to the angle 90°. Given any right triangle with legs a a a and b b b and hypotenuse c c c like the above, use four of them to make a square with sides a + b a+b a + b as shown below: This forms a square in the center with side length c c c and thus an area of c 2. c^2.
