There are two circle A and B with their centers C1(x1, y1) and C2(x2, y2) and radius R1 and R2. Task is to check both circles A and B touch each other or not.
Input : C1 = (3, 4) C2 = (14, 18) R1 = 5, R2 = 8 Output : Circles do not touch each other. Input : C1 = (2, 3) C2 = (15, 28) R1 = 12, R2 = 10 Output : Circles intersect with each other. Input : C1 = (-10, 8) C2 = (14, -24) R1 = 30, R2 = 10 Input : -10 8 14 -24 30 10 Output : Circle touch each other.
Distance between centers C1 and C2 is calculated as C1C2 = sqrt((x1 - x2)2 + (y1 - y2)2). There are three condition arises. 1. If C1C2 == R1 + R2 Circle A and B are touch to each other. 2. If C1C2 > R1 + R2 Circle A and B are not touch to each other. 3. If C1C2 < R1 + R2 Circle intersects each other.
Circle touch to each other.
