Draw an X.
Yes. Consider the two angles in the letter Z (or N). The diagonal line is common but the angles do not share a vertex.
is it possible to draw a triangle with angles 150 20 and 20°
It will be right angle triangle
No it is not possible to draw 1 triangle with 2 right angles because the angles in a triangle should equal to 180 degrees
No, it is not.
Yes. Consider the two angles in the letter Z (or N). The diagonal line is common but the angles do not share a vertex.
Yes (supposing that by side you mean ray...angles don't have sides because they are 2D, not 3D.) If you have a point and you draw four random rays from that point, that only meat at that point, then you would have created four angles. The two angles on opposite sides of the point will share a vertex, but not a RAY.
Extend both rays beyond the other side of the vertex.

it is not possible
No
No, it is not.
draw two angles in three common points
Yes if they are right angles
yes it is possible
