Source sentences:
text: It is also part of the family of 8 convex deltahedra (because it is convex and all its faces are equilateral triangles), and it is the first member of the infinite family of pyramids (one of the vertices shares identical edges with all the other vertices, which are arranged as a regular polygon).
text: Two faces are equilateral, lie on parallel planes, and have a common axis of symmetry.
text: Since each face of the tetrahedron is an equilateral triangle, the surface angle = 60
text: A tetrahedron is composed of four equilateral triangular faces.
text: Each face is an Equilateral Triangle
text: Faces: equilateral triangles Height (h):
text: Among them are five of the eight convex deltahedra, which have identical, regular faces (all equilateral triangles) but are not uniform.
text: In colloquial and chemical use, however, 'tetrahedron' typically implies the 'regular tetrahedron', where all four faces are equilateral triangles.
text: Its faces are equilateral triangles.
text: If the faces of a disphenoid are equilateral triangles, it is a regular tetrahedron with T d tetrahedral symmetry, although this is not normally called a disphenoid.
text: It has 4 faces, which are all equilateral triangles.
text: A tetrahedron is said to be regular when all its four faces are equilateral triangles.
text: This definition rules out, for example, the square pyramid (since although all the faces are regular, the square base is not congruent to the triangular sides), or the shape formed by joining two tetrahedra together (since although all faces of that triangular bipyramid would be equilateral triangles, that is, congruent and regular, some vertices have 3 triangles and others have 4).
text: All faces of a regular tetrahedron are equilateral triangles.
text: Note: A regular tetrahedron, which has faces that are equilateral triangles, is one of the five platonic solids.
text: : Two faces are equilateral, lie on parallel planes, and have a common axis of symmetry.
text: It is not possible for all triangular faces to be equilateral.
text: The hexagonal faces are equilateral but not regular.
text: The hexagonal faces are equilateral but not regular.
text: An altitude on a face is also a median (because the faces are equilateral).
text: Each face is an equilateral triangle.
text: A regular tetrahedron is a triangular pyramid with 4 equally sized faces, each face being an equilateral triangle, in this case with a 10 in side.
text: Each face is an equilateral triangle with a base 10 and vertical height 8.66 in
