Explaining The Universe on Instagram: "A dodecagon is a twelve-sided polygon. It has twelve edges and twelve vertices. In a regular dodecagon, all sides and angles are equal, with each interior angle measuring 150 degrees. The sum of all the interior angles in a dodecagon is 1,800 degrees, Dodecagons are often used in geometry, architecture, and design because of their symmetry and circular appearance when regular. They can also appear in engineering and mathematics problems involving rotational

Phyxon on Instagram: "🧠 “Ever wondered why the area of a circle is πr² — not just because they said so?” 🤔 Here’s how the formula for the area of a circle isn’t magic — it’s pure geometry & calculus 🌀 We take a circle and divide it into infinitely thin slices (sectors) — like cutting a pizza 🍕 When rearranged, those slices form a shape close to a rectangle, where: The height = radius (r) The base = half the circumference = πr So, Area = base × height = (πr) × r = πr² That’s how the area of a

mathswithmuza on Instagram: "A sphere is one of the most perfectly balanced shapes in three-dimensional space. It is formed by all the points that are exactly the same distance from a central point, known as the center. This distance is called the radius. Because of this property, a sphere has no edges, corners, or flat surfaces—it is completely smooth and symmetrical in every direction. We can see spheres all around us in nature and everyday life, such as in planets, bubbles, and sports balls.
