1. Create the geometries from P1 to P2 using all the coordinates system methods. You need to use the Line tool to create the geometries. Where required you need to use the circle tool.
AIM:
To Create the geometries of the given drawings using all the coordinates system methods.
COORDINATE SYSTEMS:
There are three methods of coordinate systems, they are
- Absolute coordinate systems
- Relative rectangular coordinate systems
- Relative polar coordinate systems
1. Absolute coordinate systems:
Absolute coordinates are based on the UCS origin (0,0), which is the intersection of the X and Y axes. Use absolute coordinates when you know the precise X and Y values of the point.
2. Relative rectangular coordinate systems:
Relative coordinates are locations defined by their distance from a reference point. To specify relative coordinates, precede the coordinate values with an @ sign. For example, entering @3,4 specifies a point 3 units along the X axis and 4 units along the Y axis from the last point specified.
3. Relative polar coordinate systems:
To specify relative coordinates, precede the coordinate values with an @ sign. For example, entering @1<45 specifies a point at a distance of 1 unit from the last point specified at an angle of 45 degrees from the X axis.
