He said he built it “during lockdown”. It would take me more than a couple of years to build something like this. #steamlocomotive #steamtrain #livesteam #narrowgauge #modelrailway #modelrailroad"

Exploring Mathematical Creativity with Desmos

explains_.everything on Instagram: "The theorem of Pythagoras, also known as the Pythagorean theorem, is a fundamental concept in geometry that describes the relationship between the lengths of the sides of a right-angled triangle. . . The theorem states that the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. Mathematically, this is expressed as a² + b² = c², where a and b are the lengths of the two shorter sides, and c is the length of the
