Here's a breakdown:\r<BR>\n" );
document.write( "\n" );
document.write( "**1. Simple Protractor Method (Less Precise, Good for Small Areas):**\r<BR>\n" );
document.write( "\n" );
document.write( "* **Tools:**<BR>\n" );
document.write( "    * Large protractor or angle finder<BR>\n" );
document.write( "    * Measuring tape<BR>\n" );
document.write( "    * Chalk or marking paint<BR>\n" );
document.write( "* **Steps:**<BR>\n" );
document.write( "    1.  **Establish Baseline:** Accurately mark your curbline as the baseline.<BR>\n" );
document.write( "    2.  **Mark a Point:** Choose a starting point along the curbline.<BR>\n" );
document.write( "    3.  **Use Protractor:** Place the center of the protractor at the marked point, aligning the 0-degree line with the curbline.<BR>\n" );
document.write( "    4.  **Mark the Angle:** Find the 52-degree mark on the protractor and make a small mark on the ground.<BR>\n" );
document.write( "    5.  **Create Line:** Use the marked point and the 52-degree mark to draw a line with chalk or marking paint.<BR>\n" );
document.write( "    6.  **Repeat:** Repeat this process at various points along the curbline to create parallel lines.<BR>\n" );
document.write( "* **Limitations:** This method is prone to errors, especially over longer distances. Small inaccuracies in the protractor placement will accumulate.\r<BR>\n" );
document.write( "\n" );
document.write( "**2. Trigonometry and Measuring (More Precise):**\r<BR>\n" );
document.write( "\n" );
document.write( "* **Tools:**<BR>\n" );
document.write( "    * Measuring tape (long)<BR>\n" );
document.write( "    * Calculator (with trigonometric functions)<BR>\n" );
document.write( "    * Chalk or marking paint<BR>\n" );
document.write( "    * String line or straight edge<BR>\n" );
document.write( "* **Steps:**<BR>\n" );
document.write( "    1.  **Establish Baseline:** Accurately mark your curbline.<BR>\n" );
document.write( "    2.  **Mark a Point:** Choose a starting point along the curbline.<BR>\n" );
document.write( "    3.  **Measure a Distance:** Measure a known distance along the curbline from the starting point (e.g., 10 feet).<BR>\n" );
document.write( "    4.  **Calculate Offset:** Use the tangent function to calculate the offset distance.<BR>\n" );
document.write( "        * `offset = distance * tan(52 degrees)`<BR>\n" );
document.write( "        * tan(52) is about 1.2799. So for every 10 foot of baseline, the offset is about 12.8 feet.<BR>\n" );
document.write( "    5.  **Mark Offset:** Measure the calculated offset distance perpendicular to the curbline and mark the point.<BR>\n" );
document.write( "    6.  **Create Line:** Connect the starting point on the curbline with the offset point to create the 52-degree line.<BR>\n" );
document.write( "    7.  **Repeat:** Repeat this process at various points along the curbline, ensuring the offset measurements are consistently perpendicular.<BR>\n" );
document.write( "* **Advantages:** This method is more accurate than the protractor method, especially for longer lines.\r<BR>\n" );
document.write( "\n" );
document.write( "**3. Using a Transit or Theodolite (Highly Precise):**\r<BR>\n" );
document.write( "\n" );
document.write( "* **Tools:**<BR>\n" );
document.write( "    * Transit or theodolite (surveying equipment)<BR>\n" );
document.write( "    * Tripod<BR>\n" );
document.write( "    * Measuring tape<BR>\n" );
document.write( "    * Chalk or marking paint<BR>\n" );
document.write( "* **Steps:**<BR>\n" );
document.write( "    1.  **Set Up Transit:** Set up the transit on a tripod at a starting point.<BR>\n" );
document.write( "    2.  **Establish Baseline:** Align the transit with the curbline.<BR>\n" );
document.write( "    3.  **Set Angle:** Set the transit to 52 degrees.<BR>\n" );
document.write( "    4.  **Mark Points:** Use the transit's line of sight to mark points at intervals along the 52-degree line.<BR>\n" );
document.write( "    5.  **Create Line:** Connect the marked points with chalk or marking paint.<BR>\n" );
document.write( "    6.  **Repeat:** Move the transit and repeat the process for other lines.<BR>\n" );
document.write( "* **Advantages:** This method is the most accurate, as transits and theodolites are designed for precise angle measurements.\r<BR>\n" );
document.write( "\n" );
document.write( "**4. Using a Construction Laser with Angle Capabilities (Precise and Efficient):**\r<BR>\n" );
document.write( "\n" );
document.write( "* **Tools:**<BR>\n" );
document.write( "    * Construction laser with angle setting capabilities.<BR>\n" );
document.write( "    * Tripod.<BR>\n" );
document.write( "    * Measuring tape.<BR>\n" );
document.write( "    * Marking paint.<BR>\n" );
document.write( "* **Steps:**<BR>\n" );
document.write( "    1.  **Set up laser:** Set up laser on tripod.<BR>\n" );
document.write( "    2.  **Establish Baseline:** Align the laser with the curbline.<BR>\n" );
document.write( "    3.  **Set Angle:** Set the laser to 52 degrees.<BR>\n" );
document.write( "    4.  **Mark Lines:** The laser will project a line at the correct angle, which you can then mark.<BR>\n" );
document.write( "    5.  **Repeat:** Move the laser as needed.<BR>\n" );
document.write( "* **Advantages:** Very accurate and fast.\r<BR>\n" );
document.write( "\n" );
document.write( "**Important Considerations:**\r<BR>\n" );
document.write( "\n" );
document.write( "* **Accuracy:** For parking lot lines, a moderate level of accuracy is usually sufficient. However, for critical applications, use a transit or laser.<BR>\n" );
document.write( "* **Safety:** Wear appropriate safety gear, such as safety glasses and high-visibility clothing.<BR>\n" );
document.write( "* **Weather:** Wind and rain can affect accuracy, especially when using string lines or lasers.<BR>\n" );
document.write( "* **Local Regulations:** Check local regulations for parking lot line specifications.\r<BR>\n" );
document.write( "\n" );
document.write( "For most parking lot applications the trigonometry method or a construction laser will work very well.<BR>\n" );
