Look at the figure below: a circle is shown with the center o. op is a segment joining center o to a point p on the circle. mn is a line touching the circle in point p. line st is shown intersecting the circle in points q and r. which is the tangent to the circle? segment op line st line mn segment qr

Line MN

Step-by-step explanation: Line MN is tangential to the circle at point P. This means that Line MN touches the circle at exactly one point, point P without entering the circle's interior. Tangents are straight line and the point at which Line MN touches the circle is known as the point of tangency. This tangent is perpendicular to the radius of the circle at the point of tangency (point P). Tangents are also base principles to many theorems, constructions and proofs.

i’m here for points.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
