Explain on Instagram: "Geometry isn’t just a subject on paper — it’s a powerful tool that shapes the world around us. In this clip, simple sand becomes a medium to explore geometric forms, showing how lines, angles, and shapes can be created with nothing more than a stick and a steady hand. For centuries, cultures across the world have used sand to visualize mathematical ideas. Traditions like Angola’s Sona patterns used sand drawings to teach logic, symmetry, and storytelling. Even today, archi

𝐽𝑜ℎ𝑎𝑛𝑛. on Instagram: "Geometry is a branch of mathematics that studies the shapes, sizes, spatial arrangement of bodies and their properties, from points and lines to complex shapes and spaces, exploring the relationships between them, such as equality, the position «between», and transformations. It originates from the ancient measures of the «Earth» (geo-metria) and studies abstract objects (point, straight line, plane), as well as real objects, distracting from their physical properties
