Rotate clockwise 900

Rotate this shape clockwise 90 0 about the point c.

Rotate this shape clockwise 90 0 about the point c.

Rotate this shape counter-clockwise 1800 about the point c.

Rotate this shape counter-clockwise 1800 about the point c.

Page 21 You will be given copy paper for this task. Using your copy paper, trace Triangle ABC. TASK 1: Perform a 90 degree clockwise rotation using Point A as your center of rotation. Draw your new figure after the rotation. Label this triangle A’B’C’. TASK 2: Perform a 180 degree rotation using Point B as your center of rotation. Draw your new figure after the rotation. Label this triangle A’’B”C”.

Page 23 Translate the Triangle shown 3 units down and 9 units right. Draw and label your new figure A’B’D’. A’ D’ B’

Page 24 Directions: Your partner will describe a translation that involves at least two steps. Example: Translate down 4 units, then translate right 7 units. You will write down their steps, then perform the translation. Sketch and label the new triangle as A’B’C’.
