The following two column proof with missing justifications proves the Pythagorean? Draw an altitude from point C to AB^- Let BC^- = a CA^- = b AB^- = c CD^- = h DB^- = y AD^- = x y – x = c c/a = a/y; c/b = b/x a^2 = cy; b^2 = cx

Fill in the missing justifications in the proof outline belows. A line will get a + next to it once you have entered a correct justification. If the justification is incorrect, you’ll get a ? or ax. Carnap will try to tell you what’s wrong: hover the cursor over the ? or x to see
