Question

Prove that length of tangents drawn from an external point to a circle are equal use above theorem find the length of ad be cf

Answer 1

To prove PT=QT Proof: Consider the triangle OPT and OQT. OP=OQ ∠OPT=∠OQT=90∘ OT=OT (common side) Hence by RHS the triangles are equal. Hence PT=QT Hence Proved.

Answer 2

Answer:

To prove PT=QT

Proof: Consider the triangle OPT and OQT.

OP=OQ

∠OPT=∠OQT=90∘

OT=OT (common side)

Hence by RHS the triangles are equal.

Hence PT=QT

Hence Proved.
