Two Dimensional Geometry

True or False:  A Rotation is a type of 'Rigid Transformation'.

• True:  A Rotation retains the pre-image's shape and size.

• False: A Rotation enlarges the pre-image's shape.

What is a Cylinder?

• Central part of a reciprocating engine or pump, and space in which a piston travels.

• Symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares.

• A solid geometric figure with straight parallel sides and a circular, or oval, cross section.

What is a Cone?

• A solid or hollow geometric figure  that tapers from a circular or roughly circular base to a point.

• Symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares.

• A solid geometric figure with straight parallel sides and a circular, or oval, cross section.

What is the formula for a Sphere figure?

• V = ⅓πr³

• V = ⅓πr²h

• V = ⁴/₃πr³

What is a Sphere?

• A round geometric solid, or its surface, with every point on its surface equidistant from its center.

• Symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares.

• A solid geometric figure with straight parallel sides and a circular, or oval, cross section.

What is a geometric net?

• A net is the shape that is formed by unfolding a three-dimensional figure. In other words, a net is composed of all of the faces of the figure.

• Free from all charges or deductions: such asa : remaining after the deduction of all charges, outlay, or loss

• They are devices made from fibers woven in a grid-like structure, and are usually meshes formed by knotting a relatively thin thread.
