Question

How was pre-image ABC transformed to create image AꞌBꞌCꞌ? A. 90° clockwise rotation around point C B. reflection over segment BC C. translation 3 units down D. translation 3 units up

Answer 1

There are 4 main transformations: Rotation, Translation, Dilation and Reflection. Reflection is a transformation: flipping an object about a line. Reflection is distance-preserving transformation. The image has the same size as the original image ( in this case: ABC = A`B`C` ).The central line is called mirror line and here it is line BC. Answer: B. Reflection over segment BC.
