The last square year was 1936, 89 years ago. 2. It's a product of two squares: 9 2 x 5 2 =2025 3. It's the sum of three squares: 40 2 +20 2 +5 2 =2025 4. It's the sum of the cubes of numbers from ...

What it means is that in a right triangle (where one angle equals 90°), the sum of the squares of two sides equals the square of the hypotenuse (the longest side).

When labelling a length as the hypotenuse, it can be shortened to 𝒉. is equal to the sum of the area of the squares on the other two sides. It is useful to think of Pythagoras’ theorem as \(a ...

Calculate the area of each square. The area of the largest square is the sum of the area of the other two squares. \(25~\text{cm}^\text{2} = 9~\text{cm}^\text{2} + 16~\text{cm}^\text{2}\) ...
