Westcott Plastic 180 Degree Protractor, Ruler Edge for 6-Inch Base, Back-to-School, School Supplies, Classroom Supplies

great for geometry

This is a simple protractor that is worth the price paid. I have to disagree with several of the reviews that claim that because every degree is not marked, it is not of value in most applications. By marking every 5 degrees, readings from the device can be made to 1-degree accuracy and reported that way with significant figures. You would be correct in reporting a reading as 41 degrees for example and all digits would be significant. You could not report 41.0 however. Just because it is not marked, does not mean that you cannot report the reading. With any measurement device, there is scale error when measuring, but this device is plenty accurate for applications that require measurements to the nearest degree. If you want measurements to the nearest 0.1 degree, then you need a different device.

Here the same day and works just like I needed it to. Price was perfect. Sorry not much to say other then it was what I needed it to be.

It was a dark and dreary time in my day-to-day world. Lines and arcs were askew and catawampus, much like my personal life. I couldn't find direction. An angle to drive my career or energy. Then, into my field of vision came the ACME UNITED 11200 Westcott 6-Inch Plastic 180 Degree Protractor, Clear. The only thing clear to me was that I needed this right now. Nothing else mattered. I became mad to a measure that had previously been unknown to me. The degree to which this changed the course of my fate is immeasurable. At least it would have been had I not received it. Thank you Acme United. You are doing God's work.

This is plastic so it could break, but it is good if you just need a basic protractor. It is somewhat large, so you may need to extend lines when measuring angles.

See through, not a scratch on it! Great functional design. I’m not sure it would be durable enough for younger students who would not be careful with it.

As a hobby I make architectural models. When doing layout on the foam core that I use for walls I often need to replicate the pitch of a roof, or the angle of a wall relative to another. The markings are clear and crisp - good for my (ahem) old eyes.

4th grader needed a protractor and this is like the one I used when I was a kid. #’s are easily seen and clear is best.

It’s a basic protractor, but it’s sturdy and accurate. Clear markings, good transparency, and compact size

It's a basic protractor. How can you go wrong for 88 cents? It is bigger than the average size used in schools, but good for teachers to use to model with a group of students.

Great large and clear view protractor for kids school. Beats all those small ones in dollar store kits. Add-on Amazon price is superb.

Plus gros de ce que je m’y attendais mais très bonne qualité

Strong and overall sturdy product. Difficult to use to find angles on smaller objects.
