Reflection Questions:

  1. Click on each "Show construction objects" button to determine how the sketches were made so that the dynamic objects retain their various properties.

  1. Are all squares rectangles?  Are all rectangles squares?

  1. How do you make a rhombus?
    • Can you make a rhombus from a parallelogram? 
    • Can you make a rhombus from a kite?
    • Can you make a rhombus from a trapezoid?

  1. Are all trapezoids parallelograms, or are all parallelograms trapezoids?

  1. Develop a GSP sketch to make the following:
    • A parallelogram
    • A rhombus
    • A square
    • A trapezoid

HINT: Review the properties of the side lengths for each figure.
