Question

1) prove that the tangents drawn to
la crcle from on External point
Equal
2) prove that the tongent at any
pont of a Cicle is perpendicular
to the radius through the point
Contact
3) prove that the tongenta drawn
at the end of a dometer of a
circle are parallel.​

Answer 1

Answer:

The lengths of tangents drawn from an external point to a circle are equal

Construction: Join OA, OB, and OP. It is known that a tangent at any point of a circle is perpendicular to the radius through the point of contact. Thus, it is proved that the lengths of the two tangents drawn from an external point to a circle are equal. The length of tangents drawn from any external point are equal.
