Question

The key idea of the transformation called translation is _____.
 the object and its image have opposite orientations
 the rotating of a plane about a fixed point
 the object moves the plane a certain angle measure
 the gliding or sliding of every point in the plane the same direction

Answer 1

Answer:

D. The gliding or sliding of every point in the plane in the same direction.

Step-by-step explanation:

We know that 'Translation' is a rigid transformation in which the image or figure is moved in any direction'.

Now, since an image in the co-ordinate plane is formed by a number of co-ordinate points.

This means that when we translate a figure, we shift all the points responsible in making the figure in the same direction.

Hence, the key feature of a translation is the gliding or sliding of every point contributing to the figure translated in the same direction.
