  1. Here, we have a right triangle with legs 3 and 4. Drag the LARGE WHITE POINTS into the largest square you see. What is the length of the hypotenuse (x)? (.ggb)
     
  2. Fill in one digit per box below to create a triangle that is a right triangle. Can you do so without repeating digits? (.ggb)
     
  3. Shown below is a mystery number we'll call "r". Move the points around. As you do, carefully observe how the value for "r" changes. What do you notice? What do you wonder? (.ggb)
     
  4. Using digits -9 to 9 no more than one time each, fill in the blanks to create a system of equations whose solution is (1,1). (.ggb)
     
  5. Move the points anywhere you'd like. Then press MOVE. Then press CONTINUE (once it appears). What do you notice? What do you wonder? (.ggb)
     
  6. Interact with this app for a few minutes. What do you notice? What do you wonder? Can you build a familiar 3D solid here? (.ggb)
