Answer:
Step-by-step explanation:
We are given two concentric circles C1 and C2 with centre O and a chord AB of the larger circle C1 which touches the smaller circle C2 at the point P (see Fig. 10.8)
We need to prove that AP = BP
Let us join OP. Then, AB is a tangent to C2 at P and OP is its radius. Therefore,
OP⟂AB (Since Tangent at any point of a circle is perpendicular to the radius through the point of contact)
Now AB is a chord of the circle C1 and OP⟂AB. Therefore, OP is the bisector of the chord AB, as the perpendicular from the centre bisects the chord,
Hence AP = BP
