Problem using specified angle command

I want to draw 2 lines with specified angles from both end of a segment AB (a line with two ends). I use specified angle for this purpose. This function draws my desired angle only from one end, let say "A". My problem is how two select the vertex of the angle to be "B".

I use Persian version of GeoGebra 3.2.47.0 (June 03, 2011)

In this version, after selecting the command, I click on the segment and a box appears to ask for the angle value and whether it is clockwise or anti-clockwise. I couldn't find any option, asking for the start point of angle (the vertex)

Try this.

Produce the segment AB.

Select the given angle-tool.

Click on B then A.

Type in "45°" and check counterclockwise.

Now, try selecting first A then B.

Type "45°" and this time check clockwise.

Is this what you had in mind?

Best regards

It works as you told, only in English version, not the Persian ver. I think it is a problem only in Persian version.

It seams that it is better to rely on English version.

Hi,

I have just changed the language, on version 4.0.41.0, to Persian, and the angle tool seems to be working OK. You are using a very old version of GeoGebra; can you update it?
