similarity and transformations


the four types of transformations

#1:rotation-when you rotate a figure onto another quadrant without changing the shape or si

#2:reflection-when you reflect another image without changing the size or shape

#3:dilation: when you enlarge a image keeping the same shape

#4:translation- when you slide a figure from its origional position onto another quadrant keeping the same shape and size

how to identify similarities with transformations

step1:translate the figure so that so that the angles map onto eachother

step2: write ratios comparing the length of each side


  • after you write the ratios see if the ratios are equal
  • if the ratios are equal then that is the dilated figure
