Love of Geometry

I have fun with the world of geometry The square, the rectangle and the parallelogram Oh' the trapezoid and the rhombus The triangles, the isosceles and the equilateral All are a great tight family together The circles and ellipses are closely related The formulas of geometry try to memorize The areas and circumferences The diagonals and angles For the trigonometric functions You discover a new world The sines and cosines The tangents and arc tangents If all this is not enough to entice you Most probably now you fell in love with geometry
