إثبات تطابق المثلثات SAS,SSS:نظرية SSS، حل مسائل

The video tutorial explains how to prove triangle congruence using SSS and SAS criteria. It begins with an introduction to these congruence rules, followed by a detailed analysis of a given problem involving triangles SRT and QRT. The instructor guides through marking the diagram and applying congruence criteria based on given data, such as equal sides and midpoints. The tutorial concludes with a step-by-step proof demonstrating the congruence of the triangles using the SSS postulate.
