Short Introduction<\/h1>\n\n\n\n

Exercise 5.4 of Chapter 5, I’m Up and Down, and Round and Round<\/em>, introduces an important theorem of circles:<\/p>\n\n\n\n

Equal chords of a circle are equidistant from the centre, and chords equidistant from the centre are equal.<\/strong><\/p>\n\n\n\n

The exercise uses the Baudhāyana–Pythagoras Theorem and congruence of triangles to establish these properties.<\/p>\n\n\n\n
