Tips

To keep your geometry set in top condition, store it in the original blister pack or a pencil case to prevent scratches. When measuring angles, align the protractor's baseline with the line and the centre point with the vertex for accurate readings. For drawing parallel lines, use the set squares together with the ruler as a guide. Clean the tools with a soft, dry cloth to maintain transparency.
