Answer 1

Regular solids are 3 dimensional polygons whose sides are all of equal length and whose angles are all equal

Answer 2

$\Huge\underline\mathtt{\blue{ ANSWER}}$

In three-dimensional space, a Platonic solid is a regular, convex polyhedron. It is constructed by congruent (identical in shape and size), regular (all angles equal and all sides equal), polygonal faces with the same number of faces meeting at each vertex. Five solids meet these criteria: Tetrahedron.
