Transformation Test Part 2Translations, Reflections, and Symmetry
17-The coordinates of WXYZ are W(-2,4), X(-6,7), Y(1,2), and Z(4,-5). After a translation 6 units to the right and 3 units down, the coordinates of the image are:
W’( ); X’( ); Y’( ); Z’( )
18- Write a rule to describe the translation. ( x , y ) →
[pic]
19- Tell whether the three-dimensional object has rotational symmetry about a line and/or reflectional symmetry in a plane.
a. [pic]
b. [pic]
20-Which types of symmetry does the figure have?
[pic]
[A] rotational and reflectional [B] rotational
[C] reflectional [D] none of these
5. If possible, draw a line of symmetry for the figure. If there is no line of symmetry, please write “not possible.”
[pic]
21- Study Figures I and II.
[pic]
Which transformation of Figure I is shown in Figure II?
O A. Rotation
O B. Reflection
O C. Translation
O D. No transformation
22-Study figures I and II.

Triangle [pic] is apparently –
O A. A translation of triangle ABC across the x-axis
O B. A 90° clockwise rotation of triangle ABC about the origin
O C. A reflection of triangle ABC across the y-axis
O D. A reflection of triangle ABC across the x-axis
25. [pic] was obtained from [pic] by a rotation about the point P.
[pic]
