Circle touching externally
WebIn the given figure, PT is a common tangent to the circles touching externally at P and AB is another common tangent touching the circles at A and B. Prove that: [3 MARKS] (i) T is the mid-point of AB (i i) ∠ A P B = 90 ∘ (iii) If X and Y are centers of the two circles, show that the circle on AB as diameter touches the line XY. WebWhen two circles touch externally, the distance between their center is the sum of their radii. It gives you the system of three equations a + b = 3, (1) a + c = 4, (2) b + c = 3. (3) …
