Jessica says she doesn’t understand the Pythagorean theorem. She put numbers in for a, b, and c in the equation a2 + b2 = c2, but the equation isn’t always true. For example, when she put in a = 2, b = 3, and c = 4, she got 4 + 9 = 16, which isn’t correct. Jessica wants to know why the Pythagorean theorem isn’t working.
