question 16 of 25
which types of polygons are the faces of a tetrahedron?
a. squares
b. regular pentagons
c. equilateral triangles
d. regular hexagons

Explanation:

A tetrahedron is a polyhedron with 4 triangular faces. In the case of a regular tetrahedron, these triangular faces are equilateral triangles. Squares are faces of a cube, regular pentagons are not faces of a tetrahedron, and regular hexagons are faces of a regular hexagonal prism or other related polyhedrons but not a tetrahedron. So the faces of a tetrahedron (especially a regular one) are equilateral triangles.

Answer:

C. Equilateral triangles
