Pacific Arc's Scholastic Triangle - 12 inch - Fluorescent - 30/60 Angle - Polystyrene - Inking Edge - Technical Drawing Tools, Drafting, Architect and Engineering.

Great! Perfect for what I needed, quality good. Size is great and easy to use. The smoke color is easy to spot on the paper or table, so locating it when you need it again is great. I use it on designing houses. I like the small 30-60-90 triangles for all the smaller lines in the design process. I recommend

I use these in various sizes to set my shop tools to accurate right angles and 45-degrees for framing. I use them for my table saw, chop saw, standing circular/belt sander. They make my life MUCH easier and my work much more accurate. My life hack!

Well made, excellent

This triangle is used for my stained glass window making area. I like that it is very clear so I can see the glass and pattern underneath. This allows me to mark fine lines onto glass and lead came as I create my windows.

I love my triangle! I like that I can see through it, so I get a sense of the entire image of my artwork. I like the color - it perks me up when I'm tired. I like the size of it - perfect fit for what I'm working on.

Exactly what I wanted

I use these preformed plastic triangles to dial in the 45s on my miter saw. I have proper delve and rafter squares but they all have that lip on the bottom that gets in my way. A lot of these plastic deals are so thin they slide under the fence. This one was just right. I tested it for accuracy against my Woodpeckers squares, as I do with all things that come into my shop. This item had a slight deformation on one side that pulled it a hair away from perfect. The other edge was dead on, so I wrote “use this edge” on it with a sharpie, and it’s been great for accuracy on my saws since.

It works as it should.

I bought this thinking it was a much bigger triangle tool for my project but in reality it’s very small. It would be good for kids and math classes or just someone who does a lot of drafting on a small scale

Not to compare with old faithful Staedler. There are better quality out there .
