”Real-world” word problems often have ladders leaning against trees, houses, or other structures. In these problems, the ladder is this part of a right triangle.

• Vertex

• Leg

• It depends on the situation.

• Hypotenuse.

When testing to see if three numbers would form a right triangle, doing this guarantees the legs are on the left side of the Pythagorean Theorem equation.

• Putting the numbers in order from largest to smallest.

• Finding the roots of all the squares.

• Putting the numbers in order from smallest to largest.

• Making sure your calculator is in Scientific Mode.
