Measuring with a Ruler

This video tutorial explains how to use a ruler to measure and draw lines or segments accurately. It begins with an introduction to the importance of using a ruler and understanding the units of length, specifically centimeters. The tutorial then demonstrates how to measure objects and segments, emphasizing the need to start from zero for accurate measurements. Finally, it provides instructions on drawing segments of specific lengths, highlighting the importance of keeping the ruler steady.
