Example Questions
Example Question #350 :Grade 8
Observe the location of the black and orange parallel lines on the provided coordinate plane and identify which of the following transformations—rotation, translation, or reflection—the black lines have undergone in order to reach the position of the orange lines. Select the answer that provides the correct transformation shown in the provided image.
Reflection over the y-axis
Translation down
A
Translation down
First, let's define the possible transformations.
Rotation:A rotation means turning an image, shape, line, etc. around a central point.
Translation:A translation means moving or sliding an image, shape, line, etc. over a plane.
Reflection:A reflection mean flipping an image, shape, line, etc. over a central line.
In the images from the question, the lines were not rotated
Example Question #31 :Geometric Translations

Select the answer that provides the correct transformation shown in the provided image.
A translation down and to the left
A reflection over the y-axis
