Presentation Transcript
Warm Up Monday 4/7Plot the ordered pair in the coordinate plane. Describe the location of the point.

(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?

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. Which coordinate’s sign will change?

• B. What are the coordinates of the reflected image?

(y)

P’ (0,-3), Q’ (4,-3), R’(3,-1), T’ (-1,-1)

### 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.
