Is the following shape a right triangle?

To determine if a shape is a right triangle, you need to check if one of its angles measures 90 degrees. Alternatively, you can apply the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides (a² + b² = c²). If either condition is met, then the shape is a right triangle.
