WebIf the circles (x+1) 2+(y−1) 2=4a 2 and x 2+y 2−4x+6y−3=0 have three common tangents only, then the value of the expression a 2−2a+43, is Solution: S 1:(x+1) 2+(y−1) 2=4a 2⇒C … WebTwo circles are said to touch each other if they have only one point common – a common tangent can then be drawn to both the circles at that point. Consider the following figure, where two circles S 1 and S 2 (with radii r 1 and r 2) touch each other externally at P. In this case, the distance between O 1 and O 2 (their centers) is r 1 + r 2 ...
WebThere can be four common tangents to two circles. The tangents can be either direct or transverse. When the two circles neither intersect nor touch each other, there are four common tangents. But when they intersect there are two common tangents, both of them being direct.
