In this chapter, we will learn about “what is symmetry,” basics of symmetry in triangles with some very good examples explaining the concepts of symmetry. Next, we will have a detailed explanation of a series of theorems along its proofs and examples which includes proportionality theorems, internal divisions, and angle bisector theorems. The second section of this chapter deals with a detailed “criteria for similarity in triangles”, which is further categorized into three sections namely - AA, SSS and SAS criterion with each consisting of explanations, theorems, proofs and various number of examples.

In addition to preparing for the JEE mains and advanced exams, Cuemath Founder Manan Khurma's study material is helpful for students who are appearing for CBSE, ICSE and other State board exams.
