1.10 Transformations on Graph
In the activity above, what happens to the coordinates when the line of reflection is the (move the line of reflection and record preimage to image in this form (x,y)---->(new x, new y): x axis? y axis? line y=x?
Without graphing, use the appropriate rule to reflect preimage A (1,4) B (-1,2) C (3,0) over the: x axis? y axis? line y=x?
In the activity above, what happens to the coordinates when the figure is rotated is the (move the rotationn and record preimage to image in this form (x,y)---->(new x, new y): 90 degrees counterclockwise? 90 degrees clockwise? 180 degrees?
Without graphing, use the appropriate rule to rotate the preimage A (1,4) B (-1,2) C (3,0): 90 degrees clockwise? 90 degrees counterclockwise? 180 degrees?
(Translations without algebra rules)Translation using a vector, move the vector to observe the direction and magnitude of the translation.
Translation using an algebra rule: change the rule to see the translation (slide).
Without graphing, use the appropriate rule to translate the preimage A (1,4) B (-1,2) C (3,0) 3 spaces right, 2 down? (x,y)----->(x-2, y+1)?
