5 True/False questions

Circle → A siple closed surface whose base is a simple closed surface and whose lateral surfaces slopes up to a vertex that is called the apex

Rectangle → A siple closed surface whose base is a simple closed surface and whose lateral surfaces slopes up to a vertex that is called the apex

Parallelogram → Quadrilateral in which the opposite sides are parallel

Polyhedron → (The plural is polyhedra) A three dimensional object whose surfaces are composed of polygonal regions (faces, verices, edges)

Pyramid → A polyhedron whose base is a polygon ad whose faces are triangles that have a common vertex. That common vertex is called the apex of the pyramid.
