Let k1 and k2 be circles with the centres S1, S2, and the radii of lengths 5cm and 1cm consecutively. Given S1=S2, what is the mutual position of these circles?
The circles k1 and k2 are concentric.
The circles k1 and k2 intersect.
The circle k1 lies inside the circle k2.
The circle k2 lies outside the circle k1.
The circles k1 and k2 are internally tangent.
