Understanding the Pythagorean Theorem

The video tutorial explains how to find the length of the hypotenuse in a right triangle using the Pythagorean theorem. It starts with a problem involving triangle legs of two and eight units, demonstrating the calculation process. The instructor emphasizes the importance of order of operations and provides the final answer. The video concludes with a transition to the next question, suggesting a different approach for solving it.

What is the problem being addressed in question 21?

• Finding the length of the legs

• Finding the perimeter of a triangle

• Finding the length of the hypotenuse

• Finding the area of a triangle

Which side of a right triangle is the hypotenuse?

• Any side

• The side opposite the right angle

• The side adjacent to the right angle

• The shortest side

What formula is used to calculate the hypotenuse?

• c = sqrt(a^2 + b^2)

• c = a^2 - b^2

• c = a^2 + b^2

• c = a + b

If the legs of a right triangle are 8 and 2 units, what are the values of a and b?

• a = 8, b = 8

• a = 2, b = 2

• a = 8, b = 2

• a = 2, b = 8

What is the result of adding the squares of the legs (8^2 + 2^2)?

• 66

• 68

• 4

• 64

What is the approximate length of the hypotenuse when the legs are 8 and 2 units?

• 6.2 units

• 9.2 units

• 7.2 units

• 8.2 units

What is the next problem (question 22) about?

• Finding the perimeter of a triangle

• Finding the hypotenuse using a different method

• Finding the area of a triangle

• Finding the length of the legs

What method is suggested for finding the hypotenuse in question 22?

• Using the Pythagorean theorem

• Counting how far up and over

• Using trigonometric ratios

• Using the distance formula

What are the variables a and b in the context of the next problem?

• The coordinates of the points

• The angles of the triangle

• The lengths of the legs

• The lengths of the hypotenuse
