Rotation To turn a shape around a particular point.
Reflection a reflection it a transformation that flips a figure about a line. this line is called the axis of reflection.
Translation when we translate a shape, we slide it. we can slide it left or right, or up or down.
Tesselation it is a tiling pattern made by fitting together 2 dimensional shapes with no gaps or overlaps.
Polyhedron it is a three dimensional object with flat faces and straight edges
Polyhedra the plural of polyhedron is polyhedra, so we can have one polyhedron and two or more polyhedra
Face the surface of a thing, especially one that is presented to the view or has a particular function.
Edge the outside limit of an object, area, or surface.
Vertex each angular point of a polygon, polyhedron, or other shape
Tetrahedrons a tetrahedron has four vertices, four faces, and six edges
Pentahedrons a pentahedron is a square based pyramid. it has 5 vertices, 5 faces, and eight edges.
Regular polyhedra a regular tetrahedron has 4 faces. the Latin tetra means 4. the 4 faces are identical equilateral triangles. 3 faces meet at each vertex.
prism a solid geometric figure whose two ends are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
cylinder a solid geometrical figure with straight parallel sides and a circular or oval cross section.
pyramid a pyramid is a polyhedron formed by connecting a polygonal base and a point.
