Pack of 2 Large Transparent Triangle Ruler Set Square: 12 Inch- 30/60 Degree & 9 inch 45/90 Degree | Essential for School and Work use (Inch Scale)

There seems to be a bit of confusion about these squares in some of the other reviews: they're inch scale squares with 1/10th inch sub-divisions. That makes them very useful for people who work with 10x10 division imperial graph paper, or who use an engineer's scale for drafting, which is also based on 10ths rather than power of 2 divisions. If this is what you're looking for, I think you'll be very happy. For those who wanted something else, I don't know what to tell you: the listing when I purchased made it clear enough what they were. The squares themselves have good optical clarity. I've put them up against my precision rules, and the linear length markings seem to be quite accurate. I don't have a precision protractor to compare the angle measures to, but the angle marks look quite regularly spaced to my eye. A benefit of the transparent plastic is the inclusion of 1/2" and 1" offset lines off the edge, which I find highly useful. I also like that both linear scales converge exactly at the corner. For some reason that is mystifying to me, many squares have the scale stop slightly short of the corner, but maybe there's a use case for that design which I'm unaware of.

They work great.

Nothing to dislike I am using them every day the most wonderful thing about them is that they have a measuring ruler to the end which is wonderful and a pleasure to use.

These were large and sturdy. They are great for arts and crafts, and I use them a lot, though I bout them for my kid's school project.

The triangles seem nice so far. Transparent so you can line things up well and they work fine as triangles. my only gripe come in when you go to use the measurements. it has inches but the tick marks are done in tenths of inches which i found rather odd. Still able to use it but it’s definitely not traditional.

Right size. Very sturdy. Waiting to use them.

the product itself is good and if you need measure only inches or half is ok but the scale is very weird every inches is divided by 10 and not 16 ....... my daughter was using this in class and noticed it.......... completely missed this details when I got it and actually I was happy with the dimension because it's hard to find a 12 inches triangle ruler

The quality is obvious! I really enjoy using them. Sizing and weight are perfect for quick drawings and more technical detailed work!

Just right not too big or small.

They cracked. I needed it for a class for one semester so it sufficed for that. I advise to get a different brand if you need it for longer.

Arrived quickly, sturdy material. Pleased with the product.

Still generally handy but the inch markings aren’t correct. The inches are split into 10 equal sections so it works for marking out whole inches/half inches but it doesn’t have accurate lines for quarter inches or eighths. (Ruler pictured for comparison)
