Create a program to draw a line, dot and a triangle in Assembly x86

Using DOSBOX create a program that uses user input to gather coordinates depending on the shape selected. For a dot it only needs a coordinate. For a line it only needs two coordinates so that the program fills the gap between the two dots. Finally the triangle will need three coordinates and the program connects the dots to create a figure. The proyect should be sent in the .asm .obj and .exe formats.
