Interface represents smooth transition of one line to another. For search of interface it is necessary to define its points and the center then to draw the corresponding crossing. For the solution of a similar task it is necessary to arm with a ruler, a pencil and compasses.
Instruction
1. Construct interface of a right angle to the set radius. Put a compasses edge on top of a right angle and carry out an arch which has the set radius, before crossing of its line with sides of angle. Note these points And yes In which are interface points.
2. Carry out from each of them by compasses two arches with the same radius before their crossing with each other. Note this point and call letter O. It will be the center of interface. Now draw interface. For this purpose draw a circle already with center O from a point And to a point of Century.
3. Define interface of two crossed straight lines at an acute angle. Carry out from two any points on each straight line two arches by the set radius. Carry out two tangents to the turned-out circles to a point of intersection which will become the center of interface. Lower perpendiculars from this point to sides of angle which will become interface points. Carry out an arch between these points with the set radius and the center. Interface of an obtuse angle is based according to the similar scheme.
4. Draw interface of two parallel straight lines. Choose an interface point on one of straight lines. Carry out from it a perpendicular before crossing from the second straight line. As a result two points of interface And yes V. Ustanovite on compasses any radius which has to be more, than the received AV piece will turn out.
5. Carry out an arch of this radius from each point. As a result two points of intersection will turn out. Connect them to a piece which has to cross AV piece in an interface point Oh, from which carry out interface to the set radius.
6. Create interface of two circles to the set radius. In this case there can be an external, internal or combined interface. For creation of the first option it is necessary to carry out from the center of each circle by compasses two arches with a radius equal to set plus circle radius, before crossing which will become the center of interface of the Lake.
7. Connect the centers of circles to this point and find points of intersection of these lines with the line of a circle. Draw the line of interface to the set radius from one point of intersection to another.
