Question

39. Prove that length of the tangents drawn from an
extemal point to the circle are equal in length. Using
above theorem, solve the following:
In given figure, quadrilateral ABCD is circumscribed.
If GC = 3 cm, BC = 7 cm, AH = 6 cm. Find AB.

Answer 1

Step-by-step explanation:

FOR A GIVEN EXTERNAL POINT P

for a given circle

OA=OB=r

from the diagram, ∆APO and ∆BPO are right angled Triangles..at A,B respectively

So,OP becomes a common hypothenuse.

thus OB=OA,OP is a common hypothenuse soo..

AP=BP

So lengths of the tangents are equal

Answer 2

Answer:

answer will be 10cm It means AB = 10cm
