Creation of geometries by Coordinate system methods using AutoCad

ANSWERS FOR ABOVE FIGURES :

Step wise to draw the above figure :

Select line tool and specify the first coordinate point 2,1 and click enter.
we can use absolute coordinate system relative rectangular coordinate system and relative polar coordinate system.
For the next point first we use absolute coordinate system.
second point is 2,7 and next points will be as follows.
(8,7),(8,6),(3,6),(3,2),(8,2),(8,1) and last enter c for close.
For the relative rectangular coordinate system.
First point will be 2,1 and the next points are as follows.
Second point (@6,0),(@0,1),(@-5,0),(@0,4),(@5,0),(@0,1),(@-6,0).
At last enter c for close.
For the relative polar coordinate system.
First point will be 2,1 and next points are as follows.
From second point (@6<0Degree),(@1<90D),(@5<180D),(@4<90D),(@5<0D),(@1<90D),(@6<180D).
At last enter c for close.

Step wise answer for how to draw the above :

select line tool and specify the first coordinate point 2,1 and click enter.
we can use absolute coordinate system relative rectangular coordinate system and relative polar coordinate system.
For the next point first we use absolute coordinate system.
Second point is 4,8 and next points will be as follows.
(7,8),(9,1),(6,1),(6,5),(5,5),(5,1) and last enter c for close.
For the relative rectangular coordinate system.
First point will be 2,1 and the next points are as follows.
Second point taken as (@0,7), (@2,0) and locate the secont point then from there (@3,0) for fourth point we repeated
the process as (@2,0),(@0,-7) and located then from there (@-3,0),(@0,4),(@-1,0),(@0,-4).
At last enter c for close.
For the relative polar coordinate system.
First point will be 2,1 and next points are as follows.
From second point (@7<74.055D),(@3<0D),(@7<105.945D),(@3<180D),(@4<90D),(@1<180D),(@4<270D).
At last enter c for close.

STEP WISE :

For the Absolute coordinate system.
First point will be 0,0 and next points are as follows.
From second point (0,1),(2,1),(2,6),(0,6),(5,9),(10,6),(10,5),(8,5),(8,1),(10,1),(10,0).
At last enter c for close.
The enter circle radius comand and specify center of the circle as 5,4 and enter radius as 2.00 then enter.

STEP WISE :

For the relative polar coordinate system.
First point will be 1,1 and next points are as follows.
From second point (@4<90Degree),(@5<45D),(@5<315D),(@4<270D).
Enter line command and join 2 points from 1 and 2 points. and from the center 3.536 join to point 3 using line command.
From point 1 locate point with lenth 1 unit and using line command draw line of 1 unit (@1<90D) and join line to center line.
From the point 2 locate the point (7,5) and draw line of 1 unit (@1<90D) join line to center line.

STEP WISE

For the relative polar coordinate system.
First point will be 1,1 and next points are as follows.
From second point (@6<0Degree),(@2<90D) and enter c for close.
enter line command locate (3,1) draw line of (@0.667<90D) and locate (5,1) draw line of (@1.333<90D).
Using line command join cross lines as shown in figure with accurate measurment.
