What is a solid that is enclosed by polygon?
A solid shape bounded by polygons is called a polyhedron.
What is a solid formed by polygons?
A polyhedron is a solid that is bounded by polygons, called faces. An edge of a polyhedron is a line segment formed by the intersection of two faces. A vertex of a polyhedron is a point where three or more edges meet. The plural of polyhedron is polyhedra or polyhedrons.
What is a solid made up of polygon faces called?
A solid made up of polygonal regions is called polyhedron. regular polygons and the same number of faces meet at each vertex.
What is a three-dimensional figure formed by regions shaped like polygons that share a common side?
polyhedron
A polyhedron is a 3-dimensional figure that is formed by polygons that enclose a region in space.
What is an exact location in space?
A point is an exact location in space. A point is denoted by a dot.
Are solids polygons?
Platonic solid, any of the five geometric solids whose faces are all identical, regular polygons meeting at the same three-dimensional angles. Also known as the five regular polyhedra, they consist of the tetrahedron (or pyramid), cube, octahedron, dodecahedron, and icosahedron.
What is a 3d polygon called?
In geometry, a polyhedron (plural polyhedra or polyhedrons) is a three-dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices. The word polyhedron comes from the Classical Greek πολύεδρον, as poly- (stem of πολύς, “many”) + -hedron (form of ἕδρα, “base” or “seat”).
What kind of solid is bounded by polygons?

Which is the best definition of a convex polyhedron?
A polyhedron whose faces are all congruent regular polygons. convex. A polyhedron such that any two points on its surface can be connected by a line segment that lies entirely inside or on the polyhedron. If this line goes outside the polyhedron, then the polyhedron is nonconvex, or concave.
Is the base of a polyhedron a polygon?
A polyhedron in which the base is a polygon and the lateral faces are triangles with a common vertex. The intersection of two lateral faces is a lateral edge. The intersection of the base and a lateral face is a base edge. The altitude, or height, is the perpendicular distance between the base and the vertex.
What are the faces of a polyhedron called?
A polyhedron with two congruent faces, called bases, that lie in parallel planes. The other faces, called lateral faces, are parallelograms formed by connecting the corresponding vertices of the bases. The segments connecting the vertices are lateral edges.
