Rooting the concept and skills of engineering sense in Egyptian and Arabic research and studies

Geometric sense is one of the types of mathematical sense in its general concept and there is a difference between researchers in Egypt and the Arab countries about the concept of geometric sense and its main and sub-skills and there is also a confusion among researchers between geometric sense measurement tests and achievement tests in geometry. The aim of the research is to accurately define the concept of geometric sense that eliminates differences between researchers, to refute the geometric skills identified by researchers within Egypt and the Arab countries for geometric sense, which confuses geometric sense, geometric thinking, geometric proof and achievement in geometry, to identify key and sub-skills for geometric sense according to the writings of the American Council of Mathematicians NTCM so that researchers can commit to them in future research.
