Proving Pythagoras

The video tutorial explains Pythagoras' Theorem, which relates the sides of a right-angled triangle. It describes how the square of the hypotenuse equals the sum of the squares of the other two sides. The theorem is visualized using squares on each side of the triangle. Although Pythagoras did not invent the theorem, he is credited with its proof. Various proofs, including algebraic ones, are discussed. The theorem's simplicity and utility in solving complex engineering and architectural problems are highlighted, making it a cornerstone of mathematics.

What does Pythagoras' Theorem state about the sides of a right-angled triangle?

• The triangle is always isosceles.

• The hypotenuse is always twice the length of the shortest side.

• The square of the hypotenuse is equal to the sum of the squares of the other two sides.

• The sum of the angles is 180 degrees.

Why is Pythagoras' Theorem named after Pythagoras?

• He invented the equation.

• He was the first to use it in architecture.

• He was the first to develop a proof for it.

• He discovered it in ancient Greece.

Which of the following is a method used to prove Pythagoras' Theorem?

• Using calculus

• Using geometry only

• Using simple algebra

How can the area of the larger square be calculated in the proof method discussed?

• By subtracting the area of the inner square from the larger square

• By adding the areas of the four smaller triangles to the inner square

• By dividing the area of the larger square by two

• By multiplying the sides of the triangle
