In the right panel is a picture of a rectangle with a given height and width and therefore[br]a well-defined Area and Perimeter.[br][br][br]In the left panel is a graph of height vs. width, with a RED dot at a position that [br]corresponds to the height and width of the rectangle in the right panel.[br][br][br]You can change the rectangle by dragging the RED dot.[br][br]You can leave a mark at the current position by clicking the "mark this point" button.[br][br][br][you may need graph paper to answer the following questions][br][br][br] along what curve in the height-width plane are all the [br][br] ▪ squares?[br][br] ▪ similar rectangles?[br][br] ▪ rectangles of a given perimeter?[br][br] ▪ rectangles of a given area?[br][br] ▪ rectangles whose diagonal has a given value?[br][br][br]Make up another question to ask.
