The pythagorean theorem is a^2 + b^2 = c^2, with c^2 being the hypotenuse (or longest side).
So a^2 + b^2 = 26
Since we're dealing with a triangle that was cut from a square, we also know that sides a and b are the same length. So, we can simplify our equation:
2a^2 = 26
Next, try to get a by itself, first by dividing both sides by 2 and then taking the square root of both sides:
a^2 = 13
a = the square root of 13
So, the side length of each piece will be the square root of 13 (approximately 3.5 inches).
