Question

1.True or false: Change in geometry is called translation.
A This statement is false. Change in geometry is called imaging.
B This statement is false. Change in geometry is called vectoring.
C This statement is true
D This statement is false. Change in geometry is called transformation.
2. True or false: The shape before the application of the transformation is called the image.
A This statement is true.
B This statement is false. The shape before the application of the transformation is called the vector.
C This statement is false. The shape before the application of the transformation is called the translation.
D This statement is false. The shape before the application of the transformation is called the pre-image.
3. The pre-image of a translation is a line. How is the image line related to the pre-image line?
A The lines are neither parallel nor perpendicular.
B The lines are perpendicular.
C The lines are on different planes.
D The lines are parallel.
4. A pre-image of a translation is a 30° angle. What is the measure of the image angle?
A 150°
B 60°
C 30°
D 15°
5. Is the following transformation with pre-image quadrilateral ABCD and image A′B′C′D′ the result of a translation? Why or why not?
A Yes, because the transformation preserved the size, shape, and orientation of the figure.
B Yes, because the transformation only altered the size and shape of the figure.
C No, because the transformation did not preserve the size and shape of the figure.
D No, because the transformation did not preserve the orientation of the figure.
