Domino - Calculation of angles, engraved

MACHINE TRANSLATION (not authorised yet)

The mathematical domain preserves knowledge of angles, including in mathematical figures. The set contains 26 plastic dominoes, on each side there is an engraved size of the angle expressed numerically in degrees, while on the other side there is an engraved drawing on which one of the angles should be calculated (e.g. a triangle with only two marked angles, the third one marked "x"). The tiles are made of smooth plastic with rounded corners, and the values and drawings are not printed but engraved, so the dominoes can serve generations of players (the inscriptions do not clash and are unbreakable). Dimensions of each tile: 8x4 cm, rounded corners, total 26 tiles. A great way to learn through play.
