3. What Are POLAR Coordinates?
These are all DISTANCE & ANGLE.
The symbol tells the computer go this from the last point.
The “<“ symbol tells it the angle.
So 2 squares up is @2<90.

4. How Do You Draw Using POLAR Coordinates?
@1.41<45
@2<90
@1<0
@2.82<135
@1<90
@1<180
How Do You Draw Using POLAR Coordinates?
25,13
@2.82<225

5. Dealing with angle not ending in a ‘0’:
You are then dealing with Pythagorean Theorem of a2 + b2 = c2
So 1 square is 1.41
So 2 squares is 2.82
Etc…..

6. Create Your Coordinates Drawing:
Complete the coordinate practice given.
On the reverse side draw your Birth Month or Year, ex. Feb or 1972 and then plot out the coordinates, write down your coordinates on the paper provided.
You will also draw this or YOURS in ACAD next. The objective is for the Month or Year you hand draw to match your ACAD drawing.
