TRUE

A polyhedran is a 3-dimentional figure that has sides that are polygons. A polygon is a 2-dimentional figure with straight sides, a closed side.

A square is a plane figure with no volume.

Congruent means they have the same angles and side lenghts. All squares have the same angles (all at 90*) but not all the same side lenghts; a square can be 5x5x5x5 and another can be 6x6x6x6.

true

Only if the 3rd side is equal or less than 6in

A shape cannot have only one side because it would not be closed. A shape must have at least three sides to be a closed figure (no "gaps")
