2. Transformation Speed Review Get out a piece of paper or graph paper and your GREEN SHEET. There are 16 questions. You may need graph paper for a few of these (especially #9 and #10) Each question has a time limit. Some questions are longer than others. This is an INDIVIDUAL assignment. NO TALKING. Listen to the music and answer the questions. Answer each question NO MATTER the difficulty. Don’t leave any blanks. You will check your answers at the end to see how many you get correct out of 16 12 out of 16 = 75 (Proficient) 13 out of 16 = 81 (Proficient) 14 out of 16 = 88 (Proficient) 15 out of 16 = 94 (Advanced)

12. 9) Rotate triangle ABC 90° clockwise about the origin. What are the new vertices of triangle A’B’C’ ? A B C A’ ( ) B’ ( ) C’ ( )

13. 10) Rotate triangle ABC 180° about the origin. What are the new vertices of triangle A’B’C’ ? A B C A’ ( ) B’ ( ) C’ ( )

15. 11 If you reflect a figure over the y-axis, what happens to the sign of the x- and y- coordinates? If you reflect a figure over the x-axis, what happens to the sign of the x- and y- coordinates?

16. 12 The rule for rotating a figure 180° is to “change the sign of both x- and y-coordinates.” A) What other transformation has the same rule as stated above? B) Use this rule to find out the vertices of triangle A’B’C’. A (4,5)A’ ( ) B (6,2)B’ ( ) C (1,3)C’ ( )

17. 13 Fill in the blanks or circle the correct choice to make the statements true about images formed from a translation, reflection, or rotation. A) Pre-image and image are congruent. (Always, sometimes, or never) B) The size and shape CHANGE. (Always, sometimes, or never) C) The sum of the angles in the pre-image are (>, <, or =) the sum of the angles in the image. D) The lengths of the sides CHANGE. (Always, sometimes, or never)

18. 14 A)Triangle XYZ is transformed into X’Y’Z’ by moving it 6 units left and 2 units down. What transformation took place? B)Triangle XYZ has positive x- and y- coordinates Ex. (3, 4). Triangle X’Y’Z’ still has positive x- coordinates but the y-coordinates are now negative. What transformation took place?

19. 15 Triangle UNO is reflected across the y-axis forming U’N’O’. Fill in the blanks to make the statements true. > < = Angle U ____ Angle U’ Angle N ____ Angle N’ Angle O ____ Angle O’ Angle U + N + O ____ Angle U’ + N’ + O’
