# Show angel measure as "gon" - not degree and radian

solsviken shared this question 9 years ago

I have recently gone from GeoNext to GeoGebra, im must say i simply love GeoGebra and its features compared to GeoNext.

But i miss one feature that i could do in GeoNext, when i have created a measure of an angle, f.eks 90 degrees, and i want the result in "gon" instead.

In GeoNext i could simply just go to properties and add an mathematical function to the measured angle. ex. =angle(A,B,C) /0.9 (the bold part is what i could add) which resulted that the answer in degrees, gets devided by 0.9 which would give me that 90 deg is 100 gon.

Is this possible in GeoGebra in some way ?

Maybe code something in that "input"field at the bottom ?

The best thing of course would be to get it as an option in the "options --> angle units -- gon" 1

Your 'gon' sounds like what I have seen as gradian, a system where a right angle is divided into 100 units instead of 90. It is sometimes known as a metric angle measuring system.

I am wondering where or in what fields that it is normally used?

Gradian is probably the right english word for what we call "gon", 100 gon is 90 degrees, and 400 gon is a complete circle.

I would love to see that implemented in GeoGebra.
