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 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.
