the radius of the circle is perpendicular to line AB, line AB is tangent to the circle

Step-by-step explanation:

A radius is a line drawn from the center of the circle to the circumference of the circle

A diagram to show the radius:

The radius of the circle and line AB form ⊥ (perpendicular lines)

Both form angle 90 degres

A tanglent is a line that touches the circle at one point.

Line AB touches the circle at a point (the point where the radius line touches the circle)

Tangent of a circle is alays perpendicular to the radius

So from the above, we can conclude:

Since the radius of the circle is perpendicular to line AB, line AB is tangent to the circle
