A tangent drawn from a point p lying in the exterior of the circle has more length than the radius​

Answer»

Answer:

data;a circle with o and a TANGENT XY to the circle at a point p

to prove;op is perpendicular to xy

construction;draw a point q on yx other than p and join oq

proof;the point q must lie out side the circle

*oq is longer than the op of the circle is oq GREATER than op

*since for every point on the line xy except the point p.op is the SHORTEST of all the distance of the o point xy. so op is perpendicular to xy
