14.2.1. Absolute Coordinate System

Try these first

1. 1.

   Provide the absolute coordinates for a point that is 50 units right and 30 units up from the origin.

   Hint

   Start from the origin and move on the X and Y axes.

2. 2.

   If a point is at (10,15), what values would you input to specify that point in the Absolute Coordinate System?

   Hint

   Refer to the format X,Y.

3. 3.

   What is the format for specifying a point in the Absolute Coordinate System?

   • X,Y
   • X@Y
   • @X,Y

   Hint

   Remember, absolute coordinates relate directly from the origin.

4. 4.

   True or False: In the Absolute Coordinate System, the origin is always (1,1).

   • True
   • False

   Hint

   Consider where the coordinate axes meet.

5. 5.

   Twist the dimensions of a 30-unit by 50-unit rectangular garden at an angle of 45 degrees from the origin, on a drawing. Provide the absolute coordinates of each corner after rotation.

   Hint

   Consider the rotation matrix to determine new positions.

6. 6.

   Design a simple house floor plan using absolute coordinates. Include a living room, kitchen, and bathroom, specifying the coordinates of each area's corners and their proportions.

   Hint

   Ensure each room’s coordinates add up perfectly to their size.
