Projective geometry

Projective geometry is a type of geometry where shapes can be changed, or "transformed," in certain ways. Each shape can become a different shape without changing its basic form. To do this, we use a special kind of mathematics called projective geometry. In projective geometry, lines stay straight and angles stay the same no matter how you move them around. Think of it like playing with toy blocks. You can stack them up and make tall towers or spread them out into triangles and squares without ever changing the blocks themselves. That's what projective geometry is all about!
