triangle

A figure shows a triangle defined by the vertex coordinates (x1 ,y1 ) ,(x2 ,y2 ) , and (x3 ,y3 ). What command will interactively prompt a user for x and y coordinates at each of the triangle vertices. then how about draw the triangle and label it vertices. Next is compute and print the area of the triangle and its perimeter.

My solution is like this, please check for me ya...

x1=input('x1=');

y1=input('y1=');

x2=input('x2=');

y2=input('y2=');

x3=input('x3=');

y3=input('y3=');

v1=[x1 y1];

v2=[x2 y2];

v3=[x3 y3];

a=sqrt((x1-x2)^2+(y1-y2)^2);

b=sqrt((x2-x3)^2+(y2-y3)^2);

c=sqrt((x3-x1)^2+(y3-y1)^2);

if a > 0 & b > 0 & c > 0 & (a + b > c) & (a + c > b) & (b + c > a)

   s=(a+b+c)/2;
   Area=sqrt(a*(s-a)*(s-b)*(s-c))
   Perimeter=a+b+c
plot([x1 x2 x3 x1],[y1 y2 y3 y1])
   title('Triangle')
   xlabel('x axis')
   ylabel('y axis')
   text(x1,y1,sprintf('(%d,%d)',x1,y1))
   text(x2,y2,sprintf('(%d,%d)',x2,y2))
   text(x3,y3,sprintf('(%d,%d)',x3,y3))
else
    disp('Not a triangle, please reinsert')
end
