  1. 3 days ago · Convex and Concave Polygon. A convex polygon is a simple polygon that has all its interior angles less than 180^\circ 180∘. As opposed to a convex polygon, a concave polygon is a simple polygon that has at least one interior angle greater than 180^\circ 180∘. Classify these polygons as convex, concave, or neither.

  2. 5 days ago · A convex polygon is a polygon with all interior angles measuring less than 1 8 0 . A straight line drawn through a convex polygon will intersect its sides exactly twice. A concave polygon is a polygon with one or more interior angles measuring more than 1 8 0 ∘.

  4. 5 days ago · A regular polyhedron has the following properties: faces are made up of congruent regular polygons; the same number of faces meet at each vertex. There are nine regular polyhedra all together: five convex polyhedra or Platonic solids four "star" polyhedra or Kepler-Poinsot polyhedra.
