not sure how the first two pictures apply here, since they're just a single circle.
check the picture below.
the one on the left can have 3 common tangent lines, the one on the right, only two common ones.
we know XYZ is an isosceles, thus XY = YZ, the perpendicular segment bisectors of QR and QS are also equal to each other in length, because they both are segment bisectors and thus YR=RX=YS=SZ, so any perpendicular line stemming from the same length on each side will meet its counterpart right on the middle of the triangle.
