a) AB= ((xB-xA)^2+(yB-yA)2)^0.5=2r2
AC = (4+9)^0.5 = r13
CD = (9+4)^0.5 = r13
BD = (16+49)^0.5= r65
AE = (1+4)^0.5= r5
CF = yF*r2=5r2
DE = (1+25)^0.5= r26
b) M1 = (x=xA+(xB-xA)/2 , y= yA+(yB-yA)/2) => M1(2,4)
M2 = (x=xD+(xA-xD)/2 , y= yD+(yA-yD)/2) => M2(0.5 , 0.5)
M3 = (x=xE+(xD-xE)/2 , y= yE+(yD-yE)/2) => M3(-0.5 ,+0.5 )
5) AB= (6^2+1^2)^0.5 = r37
BC = ( 4^2+9^2)^0.5 = r97
BE = (2^2+3^2)^0.5 = r13
xM=xA=-4 yM=-yA= -4
xN = - xA=4 yN = yA= 4
xP = -xA = +4 yP = -yA =-4
