  ## The principle of an electric motor

Image description The image shows the main components that underlie the application of the principle of the electric motor. In order for the unseen and non-palpable electrical energy to be transformed into mechanical power, moving the rotor and caloric energy,... ## The parallelogram

The parallelogram is the convex quadrilateral with opposite parallel sides.   Properties Opposite sides are congruent two by two. Opposite angles are congruent and adjacent angles are additional (their sum is equal to 180 degrees). Its diagonals are cut into... ## The rhombus

The rhombus is the parallelogram with two consecutive congruent sides. Because the rhombus is a particular parallelogram, all the properties of the parallelogram are also valid for the rhombus.   Properties all sides are congruent; the diagonals are... ## The square

The square is the regular polygon with four sides. It is a particular case of rectangle (rectangle with equal adjacent sides) and rhombus (rhombus with right angles).   Properties: the opposite sides are parallel; all sides are congruent; all angles are right;...
