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.

Which transformation, if any, of Figure I is shown in Figure II?

O A. No transformation

O B. Reflection

O C. Rotation

O D. Translation

23- Which represents a translation of the figure?

[pic]

24.

[pic]

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]

Which indicates the correspondence of the vertices?

O A. [pic]

O B. [pic]

O C. [pic]
