An edge is a straight line as part of a polygon. It can also be the straight line joining two faces of a solid which has polygonal faces.
edge?
This line is called a radius.
A segment is part of a circle created by drawing a line from a point on the edge to another point on the edge.
Isn't it the radii?
Contour line
They form a line or edge.
Contour.
An edge is an area of a 3D figure where two faces meet to form a line segment.
This is a practical definition of a boundary, or of a line, or the corner of a solid object such as a table. -- The top of the table is bounded by the edge. -- at this boundary there is a line. --
The line that forms the edge of a figure is an edge line. Which forms the figure the has been drawn. You use this line to define a drawing or a figure.
A tangent to a circle is a line which touches the circle once. That is, it does not pass through the circle, which would mean intersecting it twice. A way to form a tangent is draw any line from the centre point of a circle to its edge. A line on the edge perpendicular (at 90 degrees to) this line will be a tangent.
