The video tutorial explains how to use the converse of the Pythagorean theorem to determine if given side lengths form a right triangle. It involves applying the Pythagorean theorem formula, where the sum of the squares of the two shorter sides should equal the square of the longest side, the hypotenuse. An example calculation is provided to illustrate the process, showing that the given sides do not form a right triangle.

What is the purpose of using the converse of the Pythagorean theorem?

• To calculate the area of a triangle

• To identify if a triangle is right-angled

• To find the perimeter of a triangle

• To determine the type of triangle

Which formula is used to verify if a triangle is right-angled?

• a^2 + b^2 = c

• a^2 - b^2 = c^2

• a + b = c^2

• a^2 + b^2 = c^2

In the Pythagorean theorem, what does the largest number represent?

• The area of the triangle

• The hypotenuse of the triangle

• The height of the triangle

• The base of the triangle

What is the result of the example calculation 49 + 196?

• 200

• 225

• 245

• 256

What conclusion is drawn from the example problem?

• The sides form a right triangle

• The sides form an isosceles triangle

• The sides do not form a right triangle

• The sides form an equilateral triangle
