Platonic Solids
by Anonymous
Rotate the five Platonic solids to count faces, vertices and edges, and check that V-E+F=2 always holds.
About this app
Platonic Solids is an interactive math learning app about the five regular polyhedra: tetrahedron, cube, octahedron, dodecahedron, and icosahedron. Explore each solid, count its faces, vertices, and edges, and verify that Euler’s formula V − E + F = 2 holds for all five. A guided challenge mode lets learners answer counting questions with step-by-step feedback.
Use cases
- Elementary students learning solid geometry
