Construct a square whose each side is 4.9 cm

To construct a square with each side measuring 4.9 cm, follow these steps: 1. **Gather Materials**: You will need a ruler, a pencil, and a compass (optional for drawing arcs). 2. **Draw the First Side**: - Use the ruler to draw a straight line that is 4.9 cm long. Label the endpoints as points A and B. 3. **Construct the Right Angles**: - At point A, use a protractor to measure a 90-degree angle. Mark a point C at a distance of 4.9 cm from A along this angle. - Repeat this at point B to find point D, also 4.9 cm away from B at a 90-degree angle. 4. **Draw the Remaining Sides**: - Connect points C and D with a straight line. This line should also measure 4.9 cm. 5. **Complete the Square**: - Finally, connect points C and D to points A and B respectively, ensuring that all sides are equal and that the angles are right angles. Now you have a square ABCD where each side measures 4.9 cm.
