Finding the Hypotenuse with the Pythagorean Theorem

This video tutorial explains how to use the Pythagorean theorem to find the hypotenuse of a right triangle. It provides instructions on using calculators to find square roots and includes several examples to practice calculating the hypotenuse with different side lengths. The video emphasizes understanding how to operate your calculator and offers step-by-step guidance for solving problems using the theorem.

What is the formula for the Pythagorean theorem?

• A + B = C

• A^2 / B^2 = C^2

• A^2 * B^2 = C^2

• A^2 + B^2 = C^2

What does the Pythagorean theorem state about a right triangle?

• The product of the two legs equals the square of the hypotenuse.

• The sum of the hypotenuse equals the sum of the other two sides squared.

• The square of the hypotenuse equals the sum of the squares of the other two sides.

• The hypotenuse equals the division of the two legs.

How do you find the square root of a number using a basic calculator?

• Type the number and press the radical sign.

• Subtract the number from 100.

• Add the number to itself.

• Multiply the number by itself.

How do you operate a calculator to find the square root if the radical sign is above a key?

• Multiply the number by 0.5.

• Press the radical sign directly.

• Add 100 to the number.

• Press the second function key then the key with the radical sign.

What is the correct way to find the square root of 165 using a calculator?

• Add 165 to itself and find the square root.

• Subtract 165 from 100 and press the radical sign.

• Enter 165 and press the radical sign.

• Divide 165 by itself and find the square root.

What is the hypotenuse length when the legs are 3 and 4 units?

• 5 units

• 6 units

• 7 units

• 8 units

In the example with legs 5 and 12, what is the sum of the squares of the legs?

• 169

What is the hypotenuse when one leg is 7 units and the other is 24 units?

• 24 units

• 25 units

• 27 units

• 26 units

If the legs of a triangle are 5 and 10 units, what is the approximate length of the hypotenuse?

• 14.2 units

• 11.2 units

• 12.2 units

• 13.2 units
