Question 885497
A(-3, 1), B(3, -1) and C(1, 3)

any two sides must be equal 

Find AB, BC,CA

L(AB) =
Distance between two points													
x1	y1	x2	y2										
													
-3	1	3	-1										
d=	{{{sqrt((y2-y1)^2+(x2-x1)^2)}}}												
d=	{{{sqrt((		-1	-	1	)^2	+	(	3	-	-3	)^2	)}}}
d=	{{{sqrt((		-2	)^2	+	(	6	)^2	)}}}				
d=	{{{sqrt((		40	)  	)}}}								
d=	6.32												
L(BC)
Distance between two points													
x1	y1	x2	y2										
													
3	-1	1	3										
d=	{{{sqrt((y2-y1)^2+(x2-x1)^2)}}}												
d=	{{{sqrt((		3	-	-1	)^2	+	(	1	-	3	)^2	)}}}
d=	{{{sqrt((		4	)^2	+	(	-2	)^2	)}}}				
d=	{{{sqrt((		20	)  	)}}}								
d=	4.47												
l(CA)
Distance between two points													
x1	y1	x2	y2										
													
-3	1	1	3										
d=	{{{sqrt((y2-y1)^2+(x2-x1)^2)}}}												
d=	{{{sqrt((		3	-	1	)^2	+	(	1	-	-3	)^2	)}}}
d=	{{{sqrt((		2	)^2	+	(	4	)^2	)}}}				
d=	{{{sqrt((		20	)  	)}}}								
d=	4.47		

CA=BC
so it is an isosceles triangle
