Tetrahedron with Horizontal Cross-Section

Topic

3D Geometry

Description

This animation depicts a tetrahedron with a horizontal cross-section. It shows how slicing the tetrahedron parallel to its base results in a triangular cross-section that decreases in size as it moves towards the apex.

Using animated math clip art like this helps students understand the internal structure of complex 3D shapes. Teachers can use this to discuss concepts such as similarity, proportions, and how cross-sections relate to the volume of a tetrahedron.

Here's a potential script for teachers: "Observe the horizontal cross-sections of this tetrahedron. How does the shape of the cross-section change as we move from the base to the apex? How might this help us understand the formula for the volume of a tetrahedron?"
