Engage NY Eureka Math 8th Grade Module 2 Mid Module Assessment Answer Key

Question 1.
Translate △XYZ along $$\overrightarrow{A B}$$. Label the image of the triangle with X’, Y’, and Z’.

b. Reflect △XYZ across the line of reflection, l. Label the image of the triangle with X’, Y’, and Z’.

c. Rotate △XYZ around the point (1,0) clockwise 90°. Label the image of the triangle with X’, Y’, and Z’.

Question 2.
Use the picture below to answer the questions.

a. Can Figure A be mapped onto Figure B using only translation? Explain. Use drawings as needed in your explanation.
No, if i translate along vector $$\overrightarrow{A B}$$ i can get the longer point of figure A to map onto the lower left point of figure B(one pair of corresponding points). But no other points of the figures coincide.)

b. Can Figure A be mapped onto Figure B using only reflection? Explain. Use drawings as needed in your explanation. Use the graphs below to answer parts (a) and (b).
No, when i connect a point of figure A to its image on figure B, the line of reflection should bisect the segment. When i connect midpoints of $$\overline{x x^{\prime}}$$ & $$\overline{y y^{\prime}}$$ i get a possible line of reflection, but when i check, figure A does not map onto figure B.

Question 3.
Reflect △XYZ over the horizontal line (parallel to the x-axis) through point (0,1). Label the reflected image with X’Y’Z’.
