Task cards for practicing the Pythagorean Theorem, each featuring a right triangle, an incorrect solution, and instructions to identify the error and solve correctly.

Two educational task cards (Card 1 and Card 2) with a blue background and white scalloped borders, each presenting a right triangle problem using the Pythagorean Theorem (a² + b² = c²) to find the value of x. Each card includes a diagram of a right triangle with side lengths, an incorrect solution with a highlighted error, and instructions to find the error and solve the problem correctly in simplified radical form.
