Move the slider all the way to the left (so only 1 right triangle shows). Be sure the center of rotation = (0,0). [br]Move the WHITE POINT and [b][color=#ff00ff]PREIMAGE[/color][/b] point anywhere you want. Then answer the following questions. Be sure to number your responses in your answer:[list=1][*]What are the coordinates of the [b][color=#ff00ff]PREIMAGE[/color][/b]? [/*][*]What is the slope of the hypotenuse of the original right triangle? [/*][*]What is the slope of the hypotenuse of the rotated right triangle? [br][/*][*]What are the coordinates of the [b][color=#ff00ff]IMAGE[/color][/b]? [/*][/list]
Move the center of rotation to (2,1). Move the [b][color=#ff00ff]PREIMAGE[/color] [/b]point to (3,5). Then slide the slider slowly to the right. In the space below, please answer the following:[br][br][list=1][*]What is the slope of the hypotenuse of the original right triangle? [/*][*]What is the slope of the hypotenuse of the rotated right triangle? [br][/*][*]What are the coordinates of the [b][color=#ff00ff]IMAGE[/color][/b]? [/*][/list]
Is there any relationship between the slope of the original right triangle and the slope of the right triangle that's been rotated 90 degrees? If so, how would you describe it?
How can we use the following data[br][list][*]slope of hypotenuse of original right triangle[/*][*]slope of hypotenuse of right triangle rotated 90 degrees[/*][*]coordinates of the [b][color=#ff00ff]PREIMAGE[/color][/b][/*][/list][br]to determine the coordinates of the [b][color=#ff00ff]IMAGE [/color][/b]of any point rotated 90 degrees about any other point (other than (0,0)) in the coordinate plane? Explain.
