The video tutorial explores application problems using the Pythagorean theorem. It begins with a scenario where Peter runs a path forming a right triangle, calculating the diagonal distance. Next, it addresses a problem involving caution tape across a barn door, using the theorem to find the tape length. Finally, it examines squares on the legs and hypotenuse of a right triangle, calculating areas and perimeters.

What is the first step in solving Peter's journey problem using the Pythagorean theorem?

• Find the area of the triangle.

• Subtract the distances.

• Draw a picture to visualize the problem.

• Calculate the total distance traveled.
