This chapter is divided into two sections. The first section focuses on the basics of circles, ratio of circumference to diameters, area of circles, chords and perpendicular bisectors of chords along with important theorems and their respective proofs. The second section focuses on chords, arcs and cyclic quadrilaterals which encapsulates in-depth fundamentals of equal and unequal chords, arcs and subtended angles and concyclic points including important theorems and proofs. At the end of this section, we have a series of exercises to test your understanding of this chapter.
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.
