What is the best way to show that the side lengths 8 feet, 16 feet, and 22 feet do NOT form a right triangle?

1. Substitute the values into the Pythagorean theorem and show that a false statement results.

2. Determine the sum of the side lengths and compare it to the Pythagorean theorem.

3.Calculate the difference between the horizontal and vertical coordinates of each pair of measurements to show the triangle is equilateral.

4.Use the coordinate plane to draw the triangle and show that it is an acute triangle.
