Question

Pls Help Choose the correct word to complete the statement: If BC intersects circle A only at point B, and mCBA = 90°, then CB is a​

Answer 1

Line CB touches circle A only at one point (point B), hence CB is a tangent.

What is a circle?

A circle is the locus of a point such that its distance from a fixed point (center) is always constant.
