Hill tetrahedron
A hill tetrahedron is a shape that's made up of four triangles stacked together in a pyramid shape like a hill. Imagine stacking four slices of pizza on top of each other, so they make a point at the top. That's kind of what a hill tetrahedron looks like.
Each of these triangles is called a face, and there are four faces in total. They all connect to each other to make the pyramid shape. You can think of each face as a flat side of the pyramid.
The hill tetrahedron gets its name because it kind of looks like a little hill or mountain. If you were standing at the bottom of the pyramid and looking up, it would seem like you were standing at the bottom of a hill and looking up at the top.
People use hill tetrahedrons in math and science. They're a useful shape because they're three-dimensional and can help us understand how objects relate to each other in space. So even though they might seem like a simple shape, they can help us understand really complex ideas!
