How can I draw lines between the points of traingle after the final formation. It is a formation control problem I want to make the plot as a moving graph how to make it?

If you want to draw the trajectories of the points, then comet would be a good fit.
x = -pi:0.01:pi;
y = sin(3*x) + 0.2*cos(4*x);
comet(x,y)
Run the code above in your Live Editor and it will generate a video of the moving trajectories. This is one of the features implemented in R2021b or later. As long as "comet" is available you can see the moving path.

How about this?:
% sample data
x0 = (0:0.05:10)';
X = repmat(x0,1,3)
X = 201×3
0 0 0 0.0500 0.0500 0.0500 0.1000 0.1000 0.1000 0.1500 0.1500 0.1500 0.2000 0.2000 0.2000 0.2500 0.2500 0.2500 0.3000 0.3000 0.3000 0.3500 0.3500 0.3500 0.4000 0.4000 0.4000 0.4500 0.4500 0.4500
Y = [sin(x0),sin(2*x0),sin(3*x0)]
Y = 201×3
0 0 0 0.0500 0.0998 0.1494 0.0998 0.1987 0.2955 0.1494 0.2955 0.4350 0.1987 0.3894 0.5646 0.2474 0.4794 0.6816 0.2955 0.5646 0.7833 0.3429 0.6442 0.8674 0.3894 0.7174 0.9320 0.4350 0.7833 0.9757
% animated line
figure;
h1 = animatedline('Color','r');
h2 = animatedline('Color','g');
h3 = animatedline('Color','b');
ax = gca;
axis(ax,[0 10 -1 1])
% Loop & visualize
for k = 1:size(X,1)
addpoints(h1,X(k,1),Y(k,1));
addpoints(h2,X(k,2),Y(k,2));
addpoints(h3,X(k,3),Y(k,3));
drawnow
end
