Write a function named triangle that uses the turtle graphics library to draw a triangle.

The functions should take arguments for the X and Y coordinates of the triangle$$s vertices, and your preferred color with which the triangle should be filled. You must demonstrate the function of your program.

Also, you have to draw $4$ triangles with $4$ different colors using the function you defined. Also, Windows must not be closed until users close the Window. Triangles should be arranged so that they do not overlap.
