How to apply the pythagorean theorem to a triangle

The video tutorial explains the Pythagorean theorem, focusing on identifying the parts of a right triangle, such as the legs and hypotenuse. It demonstrates how to apply the theorem to solve for unknown sides by using the formula a^2 + b^2 = c^2. The tutorial includes a step-by-step calculation example, showing how to subtract and take the square root to find the length of an unknown side. The lesson concludes with a brief summary of the key points covered.

What is the defining characteristic of a right triangle?

• It has three acute angles.

• It has two equal sides.

• It has an obtuse angle.

• It has a 90-degree angle.

In the Pythagorean theorem, what do the letters A and B represent?

• The perimeter of the triangle

• The hypotenuse and one leg

• The two legs of the triangle

• The angles of the triangle

How do you set up the Pythagorean theorem equation for a right triangle?

• a^2 = b^2 + c^2

• a^2 + b^2 = c^2

• a + b = c^2

• a^2 + b^2 = c

What is the first step in solving for an unknown side using the Pythagorean theorem?

• Add the squares of the known sides.

• Divide the hypotenuse by one leg.

• Subtract the square of one leg from the square of the hypotenuse.

• Multiply the known sides.

What is the final step to find the length of the unknown side in the Pythagorean theorem?

• Take the square root of the result.

• Subtract the hypotenuse from the legs.

• Multiply the hypotenuse by the legs.

• Add the squares of the legs.
