(x, y) - (3x, V) dilation with scale factor 3 B. (x,y) -> (x+3, y) translation 3 units up C. (x, V) - (x, 3y) translation 3 units right D. (x, V ) - (x,y+3) horizontal stretch by a factor of 3 E. (x, y) -> (3x, 3)) vertical stretch by a factor of 31. Circle which of the following are isometric transformations. Pre-Image a. b. C. d. 2. A student claimed that the transformation (x, )) -> (3x, y) is a rigid motion because the segment joining (5,0) to (5,2) is transformed to the segment joining (15,0) to (15,2), and both of these segments have the same length. Explain the student's error. For question 3, draw the image of A ABC after a translation along v. For questions 4 & 5, draw the preimage and image of each triangle under the given translation. 3. 4. 5.
