Which step should be used to prove that point A is equidistant from points C and B?

point b+c/2= a

Step-by-step explanation:

for example let  b=6 c=2  

its obious that the mid of c and b is 4 so if we get a =4 its verified that

b+c/2= a

so = 6+2/2=8/2=4

hence proved that relation of a equidistant from points b and c through the formula b+c/2=a
