The all-in-one PolyMath is the clever maths instrument that does the lot. It’s a compass, ruler, protractor, setsquare and parallel line stencil in one handy tool. Guaranteed Irish and exam approved.
To draw a circle:
- Decide on the radius.
- Find two holes this distance apart.
- Place the point of a pencil in one hole and hold it in position.
- Rotate the Poly Math with another pencil in the second hole.
The poly Math is accurate, small, light, flexible – but not unbreakable instrument and a safe compass. It can replace any instrument you lose (if you have a set), can replace the set and is approved for State Exams.
