public static Map validateTriange(int a,int b,int c)
{
Map props = new HashMap();
boolean isValidTriangle;
int bigSide = a;
if(bigSide<b){bigSide = b;}
if(bigSide<c){bigSide = c;}
boolean isSpecial = false;
if((a+b+c-bigSide)>bigSide)
{
props.put("VALID","YES");
}
else
{
props.put("VALID","NO");
return props;
}
if(a == b||b==c||c == a)
{
props.put("ISOSCELES","YES");
isSpecial = true;
}
if(a == b && b == c)
{
props.put("EQUALATERAL","YES");
isSpecial = true;
}
if(((a*a+b*b+c*c)-bigSide*bigSide) == bigSide*bigSide)
