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.
Step-by-step explanation:
pls give brainliest
A tangent line intersecting with a radius always creates a right angle.
A tangent line intersects with a circle at only one point.
This point is referred to as the point of tangency.
When a radius is drawn to intersect with the tangent line at the point of tangency, then the angle at that point of intersection is a right angle i.e. the measure of the angle is 90 degrees.
This is so because both lines (i.e. the radius and the tangent line) are perpendicular lines.
Hence, the text that completes the statement is right angle.
