How to Use a Ruler

Using a ruler is essential for drawing straight lines accurately.
Follow these steps:

  • Position the "0" point of the ruler at the start of the line you want to measure.
  • Place the ruler carefully on the line and first measure the centimeters, then the millimeters using the small lines.
  • Remember, there are 10 millimeters in 1 centimeter (1cm = 10mm).

Here is an image depicting a ruler and straight lines for measurement:

Measuring Correctly

When measuring, remember to round up or down accurately:

  • If a measurement is 5mm or above, round it up to the nearest whole centimeter. For example, 10cm 5mm is approximately 11cm.
  • Conversely, if a measurement is less than 5mm, round it down. For instance, 10cm 4mm would be approximately 10cm.

Refer to the image below for examples of measurements:
