Connecting point in Matlab

Good evening,

after i ran this program, and selected these three points from the image, how do i connect them? As seen in image.

imshow (I) 
uiwait(msgbox('Idenitfy three points on the leaflets that indicate the begining of a leaflet, a point where the leaflets meet and the end of the other leaflet. Press Enter when finished.'));
mousePointCoords = ginput;
% plot the mouse point coordinates on the figure
plot(mousePointCoords(:,1), mousePointCoords(:,2),'b.','MarkerSize',8);

Good evening,

After i connected the points, how would i find the angle between the lines?

Thank you

imshow (I) 
hold on
uiwait(msgbox('Idenitfy three points on the leaflets that indicate the begining of a leaflet, a point where the leaflets meet and the end of the other leaflet. Press Enter when finished.'));
mousePointCoords = ginput(3);
% plot the mouse point coordinates on the figure
plot(mousePointCoords(:,1), mousePointCoords(:,2),'b.','MarkerSize',8);
plot(mousePointCoords(:,1), mousePointCoords(:,2),'b','LineWidth',3);

Read about plot..already you are plotting using markers...change the markers to line thats it.
