### ⭐⭐⭐⭐⭐ Perfect tool
*by E***C on July 19, 2025*

This dude the trick. The adjustable arm is great for setting consistent angles.

### ⭐⭐⭐⭐⭐ Great. Because it is clear
*by J***Z on May 14, 2026*

### ⭐⭐⭐⭐⭐ Great little protractor
*by G***S on April 23, 2021*

I sell my notes because I take thorough ones. And while a protractor isn't strictly necessary for diagrams in calculus, as someone who can't even draw a straight line or a circle that doesn't look like a deflated balloon, having a straight edge and circular edge makes my notes look more professional and attractive. You can also detach the angled arm when you need the inner semi-circle edge. The plastic is of high quality, doesn't shatter or scratch easily, and the best part? I take my notes on a digital notebook (ReMarkable II) and the pen and surface don't bug out when the protractor is used (though that might be more praise for the ReMarkable than the protractor - but the point is that the protractor is digital-surface friendly.) It's great. If you need a nice tight little trig/calculus protractor, this guy will deliver.
