Answer:
data÷o is the centre of the circle
p is the point lying out side the circle
pq and pr are the tangents outer circle
to prove ÷pq=pr
construction ÷ join op,or,oq
proof ÷ In triangle poq and triangle por
oq=or (radius)
op=op (common side)
angle oqp=angle orp (90°)
triangle poq=~triangle por(RHS)
pq=pr(C.p.c.t)
