Education is one of the important topics in the development of architecture and paying attention to the topics of geometry as a branch of mathematics and one of the effective factors in the formation of Iranian architecture, especially in the Islamic period, is always considered among the basic courses of this field and is one of the priorities of its education. In this research, considering the importance of the nature of phenomena in the formation and progress of sciences in the Islamic worldview and the priority of attitude in learning in the cognitive approach, the following questions are asked; What is the meaning of the word geometry and its application in architecture? and how does the concept of the word geometry in architecture affect its educational content? The following qualitative research was conducted using the descriptive-analytical method and the data was collected through library studies and based on Islamic sources. To answer the first question, by using logical reasoning, existing understandings of the word geometry and its concept in architecture are classified and Geometric-Architectural Layouts are introduced. With the help of Inference Argument, the word "Geometry" is considered equivalent to the word "Qadar", also we find out that knowing the concept of the word geometry in an incomplete form due to its wide scope, has become the basis for the existence of many interpretations and applications of the mentioned topic in architecture that in order to solve this problem, it is recommended to use "Unifying Geometrical-Architectural Layout". To answer the second question, with the help of logical reasoning, university courses, opinions of Muslim sages, perceptions and existing educational and research approaches around the concept of geometry in architecture are adapted. Then, with the help of inference reasoning, the headlines based on three approaches; exploratory-descriptive, analytical-interpretive and causal are compiled.
