Extended side

Each of a triangle's excircles (orange) is tangent to one of the triangle's sides and to the other two extended sides.

In plane geometry, an extended side or sideline of a polygon is the line that contains one side of the polygon. The extension of a finite side (a line segment) into an infinite line arises in various contexts.
