1. (2,4)
2. (-3,-1)
3. (-4,2)
4. (1,-3)
The vertices of a triangle are j(-2,1), K(-1,3) and L(0,0). Translate the triangle 4 units right (x+4) and 2 units down (y-2). What are the coordinates of the image?
Tuesday 4/8 Translation
Answer: J’ (2,-1), K’(3,1), L’(4,-2)
A. Which coordinate’s sign will change?
B. What are the coordinates of the reflected image?
Wednesday 4/9The vertices of a parallelogram are P(0,3), Q (4,3), R (3,1), T(-1,1). Relect the parallelogram in the x-axis.
A. (y)B. P’ (0,-3), Q’ (4,-3), R’(3,-1), T’ (-1,-1)
Thursday 4/10 Mini-assessment 1-3 p. T-401 http://www.bigideasmath.com
Friday: 4/11
Watch the next slides and decide if the congruent figure was created by a translation, reflection, rotation, or if it is a dilation in which the figure has changed size. There are 8 slides so number your paper 1-8.
See if you can identify the transformation that created the new shapes
REFLECTIONWhere is the
line of reflection?
See if you can identify the transformation in these pictures?
