Mathematisa | Math Animations on Instagram: "📐 Sine Rule — Visual Derivation Explained Step by Step The Sine Rule (also known as the Law of Sines) is a fundamental identity in trigonometry used to relate the sides and angles of any triangle. In this visual derivation, we explore how a / sin A = b / sin B = c / sin C emerges naturally from geometry. This reel breaks down the concept using animated diagrams, triangle projections, and clear geometric reasoning — perfect for students studying Class

Mapify World – Geography Simplified on Instagram: "Something Wrong With Google Earth – Part 79 “The Perfect Triangle in the Middle of the Ocean” 🔺🌊🛰️ In the remote waters of the South Atlantic, far from any land, islands, or shipping lanes… Google Earth shows something that should not exist: A massive, perfectly shaped triangle, darker than the surrounding ocean. No blur. No pixel glitch. No data compression artifact. Just a clean, sharp, geometric triangle — visible only from satellite view.
