Equation of circle with center (a , b) and radius, r is :
Given : a = 0 , b = - 4
Step 1 : Find the radius.
Given ( 6 , 0 ) lies on the circle. Therefore the distance between the center (0 , - 4) of the circle and ( 6 , 0 ) gives the radius of the circle.
Step 2 : Equation of circle.
I and IV are congruent and I I and III are congruent.
Congruent figures must have the same shape and measurements. Hope this helps.
