Bangun ruang platonik

Dalam ruang tiga dimensi, bangun ruang platonik adalah sebuah polihedron cembung reguler. Bangun ruang tersebut dibangun oleh sisi bangun ruang poligonal kongruen (memiliki bentuk dan ukuran yang sama) reguler (semua sudut sama dan semua sisi setara) dengan jumlah sisi bangun ruang yang sama yang bertemu di setiap Himpunan V. Lima bangun ruang yang memenuhi kriteria tersebut adalah:

Tetrahedron	Kubus	Oktahedron	Dodekahedron	Ikosahedron
Empat sisi bangun ruang	Enam sisi bangun ruang	Delapan sisi bangun ruang	Dua belas sisi bangun ruang	Dua puluh sisi bangun ruang
(Animasi) (Model 3D)	(Animasi) (Model 3D)	(Animasi) (Model 3D)	(Animasi) (Model 3D)	(Animasi) (Model 3D)
