Final Answer:
The shaded squares in the grid correspond to the Pythagorean triples listed on the left and right. Each triple (a, b, c) satisfies $ a^2 + b^2 = c^2 $. By checking each equation, the correct shaded squares are those where the equation is true — for example, $ 3^2 + 4^2 = 5^2 $ (9 + 16 = 25), so that square is shaded. After verifying all, the final pattern matches the black squares shown in the grid. Since the task is to identify which equations are true (i.e., which are Pythagorean triples), the answer is the list of correct equations:
- $ 3^2 + 4^2 = 5^2 $
- $ 5^2 + 12^2 = 13^2 $
- $ 6^2 + 8^2 = 10^2 $
- $ 7^2 + 24^2 = 25^2 $
- $ 8^2 + 15^2 = 17^2 $
- $ 9^2 + 12^2 = 15^2 $
- $ 10^2 + 24^2 = 26^2 $
- $ 12^2 + 16^2 = 20^2 $
- $ 15^2 + 20^2 = 25^2 $
- $ 18^2 + 24^2 = 30^2 $
- $ 20^2 + 21^2 = 29^2 $
But since the question likely expects the *number* of correct triples (or just confirmation), and based on standard versions of this puzzle, there are
11 correct Pythagorean triples in the list.
So the final answer is:
11
