A nonagon is a 2D shape so you cannot make a 3D nonagon!
540 degrees. you figure it out by seeing how many triangles you can make in the polygon (without crossing lines), and, because triangles equal 180 degrees, you multiply 180 times how many triangles you can make.
Yes
Yes, Four Triangles make a rectangle.
There are 6 triangles in an octagon

Yes, by intersecting them.

To make 10 triangles using 5 lines, you can arrange the lines to form a star shape, specifically a pentagram. By intersecting the lines appropriately, each intersection point can serve as a vertex for multiple triangles. The overlapping nature of the lines allows for the creation of multiple triangles within the overall shape, achieving the total of 10 triangles.
Two intersecting rays form an angle. Without two rays you do not have an angle.
There are technically many shapes that could be put into the form of a triangle, but only triangles can make real triangles (without getting into more complicated shapes).

we can make a trapezium with 3 equal triangles.
Draw a nine sided polygon.
All of them. If its truly intersecting lines, they have to form right angles. All of them. If its truly intersecting lines, they have to form right angles.
no because it has to be all equal and right angles
Yes
