Helix 10cm Protractor

This is perfect for perspective drawing. My students draw a circle, then use this device to divide the circle into several equal angles as the first step in creating buildings radiating from the center point.Delivery was fast! Item arrived a week early, even though the Helix traveled from England and went through customs.Very very pleased.

This product makes measuring and replicating angles a breeze. Great for reducing the initial layout time when drawing geometric patterns.

Before Tom-Toms, GPS’s, and other handheld items, there used to be these paper folded things called maps. Gas Stations used to sell them right on the side when you walked out. Nowadays they’re not even cared about. ‘Cept if you ever wanted to think about straight lines, brisk air and level horizons. You wouldn’t want to untie your keel and leave the dock without this and a straight ruler. Because when your communication device runs outside the reception tower, you better know what your reverse azimuth bearing is or have a double blinking light on your mast. – Waters are cold and so are the coastal winds.

Great, finally one appropriate for my 4th grader not too cheap.

A useful little protractor to have around when you need it.

it does the trick

Smaller than what would be preferred.

I ended up returning this as I found one I liked better. But it seemed perfectly fine. :)

It’s cheap and good quality highly recommended it!!

Super Hilfsmittel für die Schule. Der Pfeil daran macht es viel leichter die genaue Gradzahl abzulesen. Dadurch das es rund bis 360 Grad ist, muss man es nicht wenden oder drehen wie die halben Winkelmesser. Das macht es viel leichter.

Produit fragile, deux rapporteurs achetés , l'un des deux était déjà cassé dans son emballage.

A mí me parecía pequeño al que lo va a usar era perfecto
