NCERT Class 8 Maths Text Introduces 'BaudhayanaPythagoras Theorem'

The new volume anchors concepts in Indian sources to reduce rote learning.

Overview

  • Ganita Prakash Part 2 formally presents the right-angled triangle result under the transitional name 'BaudhayanaPythagoras Theorem'.
  • The text credits Baudhayana (c. 8th century BCE) with the earliest general statement and teaches the idea through Sulba Sutra construction on doubling a square.
  • Quoted verses and worked examples include Baudhayana triples such as 3–4–5 and 5–12–13, with a note linking these problems to Fermat and Andrew Wiles’s 1994 proof of Fermat’s Last Theorem.
  • Chapters extend historical framing to percentages via Kautilya’s Arthashastra, introduce proportionality through idli batter ratios, and add a section on fractals illustrated with Indian temple architecture.
  • NCERT says the seven‑chapter volume seeks to move beyond rote methods, and TIFR mathematician Eknath Ghate called the book’s claims reasonable.
