Transformations Practice Questions with Correct answers

Triangle RST was dilated by a scale factor of . The image, triangle R'S'T', is an isosceles triangle, with each leg measuring 8 units. What is the length of a leg of the pre-image, triangle RST? 16 units Why is the information in the diagram enough to determine that △LMN ~ △PON using a rotation about point N and a dilation? because one pair of congruent corresponding angles is sufficient to determine similar triangles Quadrilateral JKLM was dilated according to the rule DO,(x,y) - (1/2x, 1/2y)0, -4) to create the image quadrilateral J'K'L'M', which is shown on the graph. What are the coordinates of vertex J of the pre-image? (0, -4) Triangle ABC was dilated using the rule DY, 5/4. If CA = 8, what is C'A'? 10 units Which statements can be concluded from the diagram and used to prove that the triangles are similar by the SAS similarity theorem? A Read the proof. Given: AB ∥ DE Prove: △ACB ~ △DC
