Chapter 5 I am Up and Down and Round and Round NCERT Book Class Class 9 PDF (2026-27)
This chapter is dedicated to the study of circles, exploring their presence in nature and ancient art, such as the cave paintings of Odisha. It formally defines a circle as a set of points in a two-dimensional plane that are equidistant from a central point, also known as a "locus of points". Key components such as the center, radius, and chords are introduced. The text details several geometric properties, such as the fact that equal chords subtend equal angles at the center. It also explains the relationship between the center of a circle and its chords, noting that a perpendicular line from the center bisects a chord. Advanced concepts include the "angle at the center" theorem, which states the angle subtended by an arc at the center is twice the angle at the circumference. The chapter concludes with an introduction to cyclic quadrilaterals, where opposite angles sum to 180 degrees. Through activities like finding the center of a paper circle, students engage with geometry practically.
