Mathematics are underrepresented in Science and Technology museums. Using Steiner s 10 theorems on the complete quadrilateral as a common trail, the purpose of this paper has been to create an exhibit to illustrate what mathematics are and it s importance and beauty. The work has four independent sections: an analysis and description of some science and mathematic museums, the mathematics behind Steiner's 10 Questions on the complete quadrilateral with proofs, two exhibit proposals, and a creation of a web-app with Dynamic Geometry
