Question 639795
P(4,10), Q(9,-4),R(8,1)

Find the distance PQ, QR, RS

P(4,10), Q(9,-4)

x1	y1	x2	y2										
													
4	10	9	-4										
d=	{{{sqrt((y2-y1)^2+(x2-x1)^2)}}}												
d=	{{{sqrt((-4-10	)^2+(9-4)^2	)}}}
d=	{{{sqrt((-14)^2	+(5)^2	)}}}				
d=	{{{sqrt((		221	)  	)}}}								
d(P,Q)=	14.87	

 Q(9,-4),R(8,1)

x1	y1	x2	y2										
													
9	-4	8	1										
d=	{{{sqrt((y2-y1)^2+(x2-x1)^2)}}}												
d=	{{{sqrt((1-(-4)	)^2+(8-9)^2)}}}
d=	{{{sqrt((5)^2+(-1)^2	)}}}				
d=	{{{sqrt((		26	)  	)}}}								
dQ,R)=	5.10	

RR(8,1),P(4,10)
x1	y1	x2	y2										
													
8	1	4	10										
d=	{{{sqrt((y2-y1)^2+(x2-x1)^2)}}}												
d=	{{{sqrt((10-1)^2+(4-8)^2)}}}
d=	{{{sqrt((9)^2+(	-4)^2	)}}}				
d=	{{{sqrt((		97	)  	)}}}								
d=	9.85
