How can I draw a triangle with angles: 506070?
Answered
I know it could be constructed with segments command but I want to do it with triangle command.
It would be great to draw a triangle and then select the angle values in leftside menu and change it to what I want? I'm not sure if it is possible or not?
I am wondering if any data input could be done from left menu (Algebra view)?

A triangle constructed as a polygon (with the poygon tool) is defined from its vertices, that is the verices are the independant objects that the rest of the construction depends on.
GeoGebra works with constructions where independant objects are the parents of dependant objects. In general you cannot change dependant objects. You have to change the independant ones.
So it is not possible to change the angles directly without first making a construction where the angles are the independent objects.
Any independant object can be changed directly in the Algebra view by doubleclicking it or rightclicking and selecting object properties.
Thanks for your informative explanation.
Isn't it possible to define/draw a triangle based on its angles? like ASA situations?
After drawing a triangle with polygone command I try to finetune the vertices to reach the 506070 but it almost impossible to get them. On the otherhand I don't want to loose the definition by triangle as I will need it in next steps.
Draw your base segment using the segment tool.
Use the Angle with given size to draw the angle you wish.
Connect the vertex with the point with the ' on it.
Use the Angle with Given size to draw the second angle you wish.
Connect the vertex with the point with the ' on it.
The third angle has a vertex at the intersection.
