Review: "Pretty" good quality covered every base - Purchased this item for my daughter's geometry class. The triangles are a little smaller than mine were when I had geometry, but that made for storing in her calculator case very easy. The purple was what caught my daughter's eye, and it indeed was lovely. Came with more than she needed, so she should be ready for the semester. I personally liked the swing arm protractor, will make drawing angles easy.
Review: Complete and Great Quality Set - This geometry set has everything needed for school or drawing. The tools are sturdy, accurate, and easy to use.

I would definitely recommend this set.

## Questions & Answers

**Q: How do I use the divider?**
A: Usually dividers are used to transfer measurements without leaving a mark. Also you can use them to mark measurements on paper, wood and...So you measure something with your divider then you can transfer it to other things, multiple times, without measuring again and again or leaving a mark with pencils or pens.

**Q: does the divider have a screw adjustment?**
A: The metal compasses do. The 6" plastic protractor with swing arm doesn't.

**Q: How do you use the protractor with the swing arm?  What's the added benefit over using a regular protractor?**
A: Hello, Thank you fir your question. The swing arm really helps if you are trying to draw a curve with a certain angle. It can also help you to be more accurate when measuring an angle.

**Q: How do i change the the lead on the compass? it does not seem to be removal. i might do it incorrectly. thank you.**
A: There is a small knurled knob just above the lead. You have to loosen that knob; 'righty tighty, lefty loosey'. Or Counter clockwise to loosen. You find it a little bit of a challenge to grab the lead and pull it down, to adjust, or all the way out. It's graphite, which is slippery. Don't need to take the knob off, just loosen it.

### ⭐⭐⭐⭐ Bad compass
*by D***N on January 21, 2025*

The overall set is good but there is a design flaw with the compasses, the one with the twisting had a design flaw where if you open it too much, it becomes loose and hard to draw, the other compasses open too easily and shifts midway through when drawing an arc, the mechanical pencil is kind of bad because the lead doesn’t really work, the protractor asl so has a design flaw where you can’t draw the full ray, it was pretty easy to use. It’s very portable and durable and easy to organize as it comes in premade holes
