Ex 14.3, 2 Given some line segment (𝐴𝐡) Μ… whose length you do not know, construct (𝑃𝑄 ) Μ…such that the length of (𝑃𝑄) Μ… twice that of (𝐴𝐡) Μ… . We are given line segment (𝐴𝐡) Μ… We need to draw (𝑃𝑄) Μ… twice as that of (𝐴𝐡) Μ… i.e. (𝑃𝑄) Μ… = 2 Γ— (𝐴𝐡) Μ… Let’s follow these steps 1. Draw a line l mark point P on it 2. Measure (𝐴𝐡) Μ… using compass 3. Now keeping compass opened the same length. We keep pointed end at point P, and draw an arc on line l So, (𝑃𝑋) Μ… = (𝐴𝐡) Μ… 4. Now keeping compass opened the same length. We keep pointed end at point X, and draw an arc on line l So, (𝑋𝑄) Μ… = (𝐴𝐡) Μ… And (𝑃𝑄) Μ… = 2 Γ— (𝐴𝐡) Μ… Thus, (𝑃𝑄) Μ… is twice that of (𝐴𝐡) Μ… 4. Now keeping compass opened the same length. We keep pointed end at point X, and draw an arc on line l So, (𝑋𝑄) Μ… = (𝐴𝐡) Μ… And (𝑃𝑄) Μ… = 2 Γ— (𝐴𝐡) Μ… Thus, (𝑃𝑄) Μ… is twice that of (𝐴𝐡) Μ…
