Explaining The Universe on Instagram: "The Pythagorean Theorem is a fundamental principle in geometry that describes the relationship between the sides of a right-angled triangle. It states that the square of the hypotenuse—the side opposite the right angle—is equal to the sum of the squares of the other two sides. This can be written as the equation a^2 + b^2 = c^2, where a and b represent the shorter sides and c represents the hypotenuse. The theorem is used to calculate distances, design stru

WhyNot Science on Instagram: "Pythagoras Theorem Visual Proof Eminem and Trump explain why a^2 + b^2 = c^2 by rearranging four right triangles into a big square. When the areas line up perfectly, the famous Pythagoras formula appears right in front of you. ⚠️DISCLAIMER⚠️: This is not real audio/video of Eminem or Trump, and they did not actually say or sing the things you see in the video.
