A building line refers to a specified distance from the sides of the lot that shows where a given building should be built. It is very important because it provides a specified distance that a building should be from a given property.
A leader line is a thin line on a design or blueprint that is used to connect a dimension line with a particular area or point on the drawing.
the machine is able to break down
this curve is used a lot in gear design. This curve is used to get the gear tooth profile and when two gears of this profile mesh, the instantaneous contact point is only one and it moves along the curve profile. This property is known as line of action or line of Contact or pressure Line and this is why it is used extensively in gear design.

A line through a circle that does not go through the center of the circle is a secant line. A line through a circle that does go through the center is still a secant line, by the way. Compare this to a line segment that has its two endpoints on the circumference of the circle. That line segment is a cord of the circle. If that cord of the circle passes through the center of the circle, then the cord is a diameter of that circle.
No, a secant line does not pass through the center of a circle. A secant line is a line that intersects a circle in two distinct points. Only a line passing through the center of a circle is called a diameter.
The line passing through the center of a circle with two endpoints on the circle is the circle's diameter.
The line from the center of a circle to a point on the circle is the radius.
The radius is the line from the center of a circle to its circumference.
A line that goes through a circle is a secant line. (Remember that a line is infinitely long.) Anyline that passes through a circle is a secant line, whether it passes through the center of the circle or not. Compare this to a line segment with endpoints on the circumference of a circle. That segment is called a cord of that circle. If the cord of a circle passes through the center of that circle, it is a diameter of that circle, which is the longest cord of the circle.
The line from the center of a circle to a point on the circle is the radius.
If it connects the center of the circle to the edge, it is the radius. If it is a straight line that connects the edges of a circle through the center, it is the diameter.
A line segment with the center of a circle as one endpoint and the other endpoint on the circumference of the circle is a rdius of that circle.
Any line that passes through a circle and touches two points on its circumference is a secant line. (Recall that a line is infinitely long.) If the line passes through the center of the circle, it is still called a secant line. Compare this to a line segment that has its endpoints on the circumference of the circle. That line segment is called the cord of the circle. If that cord passes through the center of the circle, it is a diameter of the circle, which is the longest cord of that circle.
A line from the center of a circle to any point on the circle is called a radius.
The line segment is the radius of a circle that connects the center of a circle to any point on its circumference.
