Use the line() function. No, I don't know the (x,y) coordinates of the endpoints - you'll have to figure that out yourself. You can display your image and say "axis on" to get some idea of what the locations would be.

Try this:
x = [1 2 3];
y = [1 2 1];
line([x(1), x(2)], [y(1), y(2)], 'Color', 'b', 'LineWidth', 3);
hold on;
line([x(2), x(3)], [y(2), y(3)], 'Color', 'b', 'LineWidth', 3);
line([x(3), x(1)], [y(3), y(1)], 'Color', 'b', 'LineWidth', 3);
grid on;
ylim([0, 3]);
axis equal;
