• A segment that divides in two equal lengths another line

• The point where the tangent line and the curve meet is called the point of tangency.

• Is the point equidistant from the points on the edge

Which basic property of tangency represents this picture?

• The centres of two circumferences that are tangent are aligned with the point of tangency.

• A tangent to a circle is perpendicular to the radius at the point of tangency.

• The centre of any circumference tangent to two lines is found in the angle bisector of the angle that the two lines form.
