Question

question 9 of 10 other than squares, the polygons that can be the faces of a platonic solid are __ and __. check all that apply. a. equilateral triangles b. regular pentagons c. regular hexagons d. trapezoids e. circles f. rectangles

Explanation:

Platonic solids have regular polygons as faces. Equilateral triangles are in tetrahedron, octahedron and icosahedron. Regular pentagons are in dodecahedron. Regular hexagons and other non - regular polygons like trapezoids, rectangles cannot form Platonic solids as the angles and side - lengths won't allow for the regular, symmetrical structure. Circles are not polygons.

Answer:

A. equilateral triangles, B. regular pentagons
