Yes. Consider the two angles in the letter Z (or N). The diagonal line is common but the angles do not share a vertex.
Draw an X.
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 (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.
Draw an X.
Extend both rays beyond the other side of the vertex.

No
No, it is not.
Yes if they are right angles
It is impossible to have a triangle with 3 right angles. It is possible to draw a triangle with three right angles on the surface of a sphere: www.metacafe.com/watch/769025/270_degree_triangle_yes_3_right_angles
yes it is possible
