Locate the center of dialtion and the scale factor. List your answers on the provided lines and show all work.
Dilate ∆ABC using a center of dialtion at the origin (0,0) and a scale factor of 1/2. Label the points appropriately.
Dilate ∆ ABC using a center of dialtion of (-6,7) using a scale factor of 3. Label the points appropriately.
Which transformations must be used to map ∆WXY to ∆BCD?
In the show your work section, mark your lines of reflection, points of rotation, or centers of dilation as they would be needed (you may need all, some, or none of these).
True or False: If two triangles are congruent, then the triangles are similar.
Type whether this statement is true or false, then explain your answer with words and pictures. The Show your work section is available if you need.

The following 2 triangles in the pic below are similar. Using what you know about similar triangles solve for x.
Your answer should be x=__ and you should show all work in the show your work section for how you found x.
The following 2 triangles in the pic below are similar. Solve for x. Then, write in the missing side length of the green question mark and show how you found x in the show your work.
Your answer should be x=__ and list your value for the green question mark in the show your work seciton.

Your answer may be entered as ___ feet and you must show all work and drawings in the show your work section.
Mr. Wile and Mrs. Lindeman are standing on opposite sides of a river facing one another. Mr. Wile walks 12 meters upstream and 5 meters from the river edge and Mrs. Lindeman walks 30 meters downstream but stays at the river edge. What is the width of the river?
(The distances walked are up/down the river are not to scale)
Extra Credit: Dilated figures are similar but not congruent.
Extra Credit: Reflected figures are similar but not congruent.
