Wang Muran


1. Choose a location for P, a variable point on the line OA. 2. Check the box 'Show Q' to visualise where Q is according to the given ratio. 3. Check the box 'Show R' to visualise where R is according to the given ratio. 4. Drag the variable point P along the line OA, observe how R varies and make a conjecture (guess). 5. Check the box 'Trace R' then repeat step 4, you will see the locus of R as P varies.
