I have a diagram with angles alpha, beta, gamma. I want to show the sum of the three measures of the three angles. I want the sum to change dynamically as the sketch changes. How do I do this?
I can't seem to enter a measurement from the sketch into the spreadsheet.
I can't find this simple thing for the life of me in documentation!

To write to Cell A1
really necessary to use the spreadsheet?
Something is missing from this answer. I don't want the *symbols \alpha + \beta + \gamma in the spreadsheet--which is what I get when I follow these instructions. I want the sum of the measures of three angles.
But I don't care if it's not in the spreadsheet. Geogebra *must* have a tool to compute with measurements. How do I do it? The tutorials don't answer that. The examples given are not what I want. The 'help' files--this is typical of most software--don't really help.
an answer can only use the information given, quite mysterious where the problem is to add 3 angles
i intend the symbols \alpha + \beta + \gamma are variables of the angles
it is a common use to upload an appropriate file, this is what i am missing
Can you just type this?
