Equal Chords of Congruent Circles
Product Code : JA-MLK-4485
The Equal Chords of Congruent Circles set (SKU JA-MLK-4485) is a three-part geometry teaching aid for showing that equal chords of congruent circles subtend equal angles at the centre. As an equal chords theorem model it lets a teacher, or a small student group, compare chords and the angles they make at the centre directly, and it suits secondary-school maths labs and classroom demonstrations of circle properties.
Specifications
The set is supplied as three parts that together demonstrate one circle property, namely that equal chords of congruent circles subtend equal angles at the centre; the table lists the only details given in the product data, and the material, dimensions and finish of the parts are confirmed on the quotation.

Applications of the equal chords theorem model
In the maths lab the set is used to demonstrate and check a standard circle theorem by hand, so that students see why equal chords in circles of the same radius make equal angles at the centre before they write the formal proof in their notebooks.
- Classroom demonstration that equal chords of congruent circles subtend equal angles at the centre
- Maths lab activity on circle properties for secondary classes (CBSE/NCERT circles unit)
- Discussion of the converse: chords that subtend equal angles at the centre are equal
- Revision of chord and angle relationships before geometry problem-solving
