Plastic Protractor Math Protractors 180 Degrees, 4 Inch, Clear, Pack of 2

These protractors have the classic styling and perfection of protractors from 60 years ago. They do not attempt to 'reinvent' the protractor but provide without hubris the protracting experience that has existed for generations. The engineers at NASA used protractors like this when in school - and you can experience angles just like they did in their formative years. I can garantee this: while not every person who uses these protractors will grow up to be a NASA engineer, every NASA engineer used a protractor like this. Think about it.

They work and are made ok. No complaints and happy to have them.

The label is lined up and it is easy to use.

This is the classic design of protractor and works much better than dual function ruler/protractor designs with section cut out in middle. The lines from center point make it easier for my son to figure out angles for his math homework. He likes using this style of protractor for his homework.Only negative is that for the price paid, I would have expected thicker and higher quality plastic to resist scratching. It's over priced for what it is, but it's the classic design that works well.

These are easy to read and good for measuring and drawing angles. I took off a star because a spot on the edge of both protractors is scratched/roughed up making it difficult to draw precise straight lines. We’ve only used these a few times and are already having this issue.

For mathematics

Was expecting a bigger size traditional size, but having extended lines is a great help for accuracy.

these protractors are great! the only problem was that one of them came broken.
