Question

Converse of theorem of the angle between
tangent and secant : (Textbook page 77)
Statement : A
line
is
drawn from one end
point of a chord of a Y
circle and if the angle
0.
between the chord and
the line is half the
measure of the arc
intercepted by that
angle, then that line is a tangent to the circle.

Answer 1

Answer:

A line that intersects a circle in exactly one point is called a tangent and the point where the intersection occurs is called the point of tangency. The tangent is always perpendicular to the radius drawn to the point of tangency. A secant is a line that intersects a circle in exactly two points.
