Solve both the qns plis
Dear Student,
Q15.
We know that the tangents drawn from an exterior point to a circle are equal in length.
∴ AR = AQ (Tangents from A) ..... (1)
BR = BP (Tangents from B) ..... (2)
CQ = CP (Tangents from C) ..... (3)
Now, the given triangle is isosceles, so given AB = AC
Subtract AR from both sides, we get
AB – AR = AC – AR
⇒ AB – AR = AC – AQ (Using (1))
BR = CQ
⇒ BP = CQ (Using (2))
⇒ BP = CP (Using (3))
So BP = CP, shows that BC is bisected at the point of contact.
