Q. 33.9( 7 Votes )
The length of tangent from an external point P on a circle with center 0 is always less than OP.
Answer :
True
Consider a figure for the problem in which we have a circle with center O.
PT is a tangent drawn from external point P. Joint OT.
OT ⏊ PT [ As tangent at any point on the circle is perpendicular to the radius through point of contact]
So, OPT is a right-angled triangle formed.
In right angled triangle, hypotenuse is always greater than any of the two sides of the triangle.
So,
OP > PT or PT < OP
Hence, Length of tangent from an external point P on a circle with center O is always less than OP .
