How to draw and connect three points

Give three matrices with one row and two columns (1x2). Each matrix corresponds to a point and the two columns of each matrix correspond to the x y coordinates of the respective point. So I have three points in total. How can I draw these three points on a graph, link them through segments and label them?

x = rand(1,3) ;
y = rand(1,3) ;
plot(x,y) ;
n = 1:3 ;
text(x,y,num2str(n'))

Head = [HeadX HeadY HeadZ];
Head_1 = Head(1,1:2);
HeadX_1 = 250.8390;
HeadY_1 = 643.3690;
scatter(HeadX_1, HeadY_1);
LRCollar = [LRCollarX LRCollarY LRCollarZ];
LRCollar_1 = LRCollar(1,1:2);
LRCollarX_1 = 264.4240;
LRCollarY_1 = 341.0450;
scatter(LRCollarX_1, LRCollarY_1);
Waist = [WaistX WaistY WaistZ];
Waist_1 = Waist(1,1:2);
WaistX_1 = 281.9030;
WaistY_1 = -94.8090;
scatter(WaistX_1, WaistY_1);

Try this:
V1 = randi(9, 1, 2); % Vector #1
V2 = randi(9, 1, 2); % Vector #2
V3 = randi(9, 1, 2); % Vector #3
M = [V1; V2; V3; V1]; % Repeat First Row To Complete The Triangle
figure
plot(M(:,1), M(:,2))
axis([0 10 0 10])
ptl = sprintfc('V_{%d}', 1:3); % Numbered Vectors
ptl = sprintfc('V(%.1f,%.1f)', M(1:end-1,:)); % Vector Coordinates
text(M(1:end-1,1), M(1:end-1,2), ptl)
Experiment to get the result you want.
