Question

there are only three types of polygons that can be the faces of a platonic solid. they are ____, __, and ____. check all that apply.

a. trapezoids
b. equilateral triangles
c. squares
d. regular pentagons
e. circles
f. rectangles

Explanation:

Platonic solids are 3D shapes with identical regular polygon faces, where the same number of faces meet at each vertex. Only equilateral triangles (found in tetrahedrons, octahedrons, icosahedrons), squares (found in cubes), and regular pentagons (found in dodecahedrons) satisfy the geometric requirements for Platonic solids. Other options are either not regular polygons or cannot form such solids.

Answer:

B. equilateral triangles
C. squares
D. regular pentagons
