1. The Distance to An Unapproachable Point
This simple, but important, experiment is a fine one to do outdoors in a team competitive manner. Before the time of radar, such distances as the height of a mountain or an enemy position during a battle-that is, distances to points which cannot be practically or safely approached-were determined by the methods of geometry or trigonometry.

...change its shape and size. What do you notice about the ratio of the areas of the two figures? Can you explain why this relationship holds? applet archive(JSPDR3R.JAR) Sorry, this page requires a Java-compatible web browser. 2. What kind of relationship is there between the areas of quadrilaterals, similarly formed? Choose the four-sided polygon. Move the vertices around to explore whether the relationship you found in task 1 will still hold. How might you need to adjust your conjecture? Prove your result. 3. What kind of relationship is there between the areas of n-gons (for n = 5), similarly formed? Predict w...
