How Do I Run This Applet?

This java applet requires a java-capable browser. If you don't see the applet, Java may not be functional in your browser or on your machine.

Object of the activity

This applet allows the user to explore the world of transformations, reflections, and rotations. It allows the user to translate triangles, squares, and parallelograms on both the x and y-axes.

Controls and Output

• Clicking the New Triangle, New Square, and New parallelogram buttons draw a new triangle, square, or parallelogram on the coordinate plane.
  
  

  
  

• Translate Controls: Clicking and entering a number in the text box beside the phrase units on the X axis will let the applet know how many units to translate the figure on the X axis. Likewise, clicking and entering a number in the text box beside the phrase units on the Y axis will let the applet know how many units to translate the figure on the Y axis. Then clicking on the translate button will translate the figure.
  
  
  
• Reflect Controls: Clicking and entering a number in the text box beside the phrase across the X = will let the applet know what vertical line that you want to reflect the figure about. Likewise, clicking and entering a number in the text box beside the phrase across Y = will let the applet know what horizontal line that you want to reflect the figure about. Then clicking on the reflect button will reflect the figure.
  
  
  
• Rotate Controls: Clicking and entering a number in the text box beside the phrase degrees will let the applet know how many degrees of rotation you want to use. Then clicking on the rotate button will rotate the figure.
