Polyhedra
Tetrahedra: a solid comprised of four triangular faces; a triangular pyramid
A regular tetrahedron (one of the five Platonic solids) has four congruent equilateral triangles as faces.
Regular polyhedra: A regular polyhedron is a polyhedron whose symmetry group acts transitively on its flags. A regular polyhedron is highly symmetrical, being all of edge-transitive, vertex-transitive and face-transitive.
Pentahedra: In geometry, a pentahedron (plural: pentahedra) is a polyhedron with five faces or sides. There are no face-transitive polyhedra with five sides and there are two distinct topological types.
Cubes; a symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares.
Prisms: a solid geometric figure whose two ends are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
octahedron: a three-dimensional shape having eight plane faces, especially a regular solid figure with eight equal triangular faces.
dodecahedron: a three-dimensional shape having twelve plane faces, in particular a regular solid figure with twelve equal pentagonal faces.
icosahedron: a three-dimensional shape having twelve plane faces, in particular a regular solid figure with twelve equal pentagonal faces.
-
cylinders: a solid geometrical figure with straight parallel sides and a circular or oval cross section.
a solid or hollow body, object, or part having the shape of a cylinder.
pyramid: a solid geometrical figure with straight parallel sides and a circular or oval cross section.
a solid or hollow body, object, or part having the shape of a cylinder.
Quadrilaterals
-
-
-
pentagon
a five-sided polygon
A regular pentagon has all its sides and angles equal. Angles ad up to 540 degrees
Rhombus
a quadrilateral with both pairs of opposite sides parallel and all sides equal; a parallelogram with two adjacent sides equal in length
-
-
Diameter:a line interval passing through a circle’s centre with its end points on the circumference
The diameter is twice as long as the circle’s radius.
-
circumference: circumference (from Latin circumferens, meaning "carrying around") is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.
-
-
Vertex: in 2D shapes, a point where two straight lines meet to make an angle;
in 3D objects, a point where three or more straight edges meet to make a corner
-
Lines
-
Vertical
90 degrees. : 
Horizontal
180 degrees.
-
Paralell Line. Lines running a constant distance from one another, never intersecting in the same direction. but running in the same direction.
Perpendicular Line: at right angle(s) with another surface
Line segment: A segment of line.
Ray: a line that extends infinitely from one point.
