A geometric construction system includes at least two substantially flat panels and at least a connecting rod. Each panel has a frame piece and a pair of cover sheets. The frame piece has side walls with side edges, each of which has a basin section, and further has an inner face defining a central opening. The inner face is formed with a flange that cooperates with the inner face to define a pair of retaining grooves. The connecting rod has at least two interconnected connecting portions, each of which is complementary to and is received in the basin section. The cover sheets are respectively and fittingly received in the retaining grooves.
