Pythagorean Theorem Applications

The video tutorial explains how to solve a problem involving a ladder leaning against a house using the Pythagorean theorem. The problem is introduced with a context, and a diagram is used to visualize the scenario. The Pythagorean theorem is applied to find the missing distance from the house to the bottom of the ladder. The solution is verified by checking the calculations, ensuring the accuracy of the result.

What is the main problem Mr. Harris is trying to solve?

• Finding the height of the house

• Determining the length of the ladder

• Measuring the width of the house

• Calculating the distance from the house to the bottom of the ladder

What mathematical concept is primarily used to solve the problem?

• Geometry

• Pythagorean theorem

• Algebra

• Trigonometry

What does the diagram in the video represent?

• A house with a ladder against it

• A tree with a swing

• A car parked in a garage

• A bridge over a river

What is the length of the ladder used by Mr. Harris?

• 36 ft

• 30 ft

• 24 ft

• 18 ft

What is the height from the ground to the top of the ladder?

• 30 ft

• 24 ft

• 18 ft

• 12 ft

According to the Pythagorean theorem, what is the relationship between the sides of a right triangle?

• a^2 + b^2 = c^2

• a^2 = b^2 + c^2

• a^2 - b^2 = c^2

• a^2 + b^2 = 2c^2

What is the equation set up to find the unknown distance?

• b^2 = 18^2 + 30^2

• b^2 + 30^2 = 18^2

• 18^2 + b^2 = 30^2

• 18^2 = b^2 + 30^2

What is the value of b^2 after solving the equation?

• 1024

• 324

• 900

• 576

How do we verify the solution is correct?

• By using a different mathematical formula

• By measuring the ladder again

• By checking the calculations using the Pythagorean theorem

• By asking Mr. Harris

What is the square root of 576?

• 24

• 22

• 20

• 18
