Geo Board Circle
Product Code : JA-MLK-1907
The Geo Board Circle (SKU JA-MLK-1907) is a geoboard for teaching geometrical shapes and circle theorems with rubber bands. A circular protractor is printed in the centre around the ring of the circle, so the angles formed by the bands can be read directly. Pupils stretch bands to form chords, radii and inscribed angles and verify the angle in a semicircle, the angle at the centre and the angles subtended in the same segment. JaincoLab makes this circle geoboard for secondary maths labs.
Specifications
The board has a circle with a circular protractor printed in the centre and is used with rubber bands; the board size and peg count are confirmed on the quotation.

Circle theorems on the geo board circle
Stretching bands across the circle and reading the angles on the printed protractor lets students test each circle theorem themselves, rather than only following a written proof.
- Angle in a semicircle is a right angle
- Angle at the centre is twice the angle at the circumference
- Angles in the same segment are equal
- Angles in a segment and chords
- Drawing polygons and other shapes with bands
