A perpendicular at the end of the radius of a circle is
A perpendicular at the end of the radius of a circle is
- A. diameter
- B. tangent
- C. chord
- D. anyline
Step-by-step solution
A line perpendicular to the radius at its endpoint on the circle is tangent to the circle by definition: the radius to the point of tangency is perpendicular to the tangent line.
