Question
Line ℓ touches a circle with center O at point P. If the radius of the circle is 9 cm, answer the following.
If d(O, Q) = 8 cm, where does the point Q lie?
Solution
Here, 8 cm < 9 cm
∴ d(O, Q) < d(O, P)
∴ d(O, Q) < radius
∴ Point Q lies in the interior of the circle.

In the adjoining figure circles with centres X and Y touch each other at point Z. A secant passing through Z intersects the circles at points A and B respectively. Prove that, radius XA || radius YB. Fill in the blanks and complete the proof.
Construction: Draw segments XZ and YZ.
Proof:
By theorem of touching circles, points X, Z, Y are `square`.
∴ ∠XZA ≅ `square` ...(opposite angles)
Let ∠XZA = ∠BZY = a ...(I)
Now, seg XA ≅ seg XZ ...[Radii of the same circle]
∴∠XAZ = `square` = a ...[isosceles triangle theorem](II)
Similarly,
seg YB ≅ seg YZ ...[Radii of the same circle]
∴∠BZY = `square` = a ...[isosceles triangle theorem](III)
∴ from (I), (II), (III),
∠XAZ = `square`
∴ radius XA || radius YZ ...[`square`]
