Eureka Math Grade 8 Module 2 Lesson 2 Exercise Answer Key<\/h3>\n

Exercise 1.
\nDraw at least three different vectors, and show what a translation of the plane along each vector looks like. Describe what happens to the following figures under each translation using appropriate vocabulary and notation as needed.
\n\"Eureka
\nAnswer:
\nAnswers will vary.<\/p>\n

Exercise 2.
\nThe diagram below shows figures and their images under a translation along \\(\\overrightarrow{H I}\\). Use the original figures and the translated images to fill in missing labels for points and measures.
\n\"Eureka
\nAnswer:
\nSolutions are in red, below.
\n\"Eureka<\/p>\n

Question 1.
\nName the vector in the picture below.
\n\"Eureka
\nAnswer:
\n\\(\\overrightarrow{Q P}\\)<\/p>\n

Question 2.
\nName the vector along which a translation of a plane would map point A to its image T(A).
\n\"Eureka
\nAnswer:
\n\\(\\overrightarrow{S R}\\)<\/p>\n

Question 3.
\nIs Maria correct when she says that there is a translation along a vector that maps segment AB to segment CD? If so, draw the vector. If not, explain why not.
\n\"Eureka
\nAnswer:
\n\"Eureka
\nYes. Accept any vector that would translate the segment AB to segment CD. A possible vector is shown in red, above.<\/p>\n

Question 4.
\nAssume there is a translation that maps segment AB to segment CD shown above. If the length of segment CD is 8 units, what is the length of segment AB? How do you know?
\nAnswer:
\nThe length of CD must be 8 units in length because translations preserve the lengths of segments.<\/p>\n

Question 1.
\nTranslate the plane containing Figure A along \\(\\overrightarrow{A B}\\). Use your transparency to sketch the image of Figure A by this translation. Mark points on Figure A, and label the image of Figure A accordingly.
\n\"Eureka
\nAnswer:
\nMarked points will vary. Verify that students have labeled their points and images appropriately.
\n\"Eureka<\/p>\n

Question 2.
\nTranslate the plane containing Figure B along \\(\\overrightarrow{B A}\\). Use your transparency to sketch the image of Figure B by this translation. Mark points on Figure B, and label the image of Figure B accordingly.
\n\"Eureka
\nAnswer:
\nMarked points will vary. Verify that students have labeled their points and images appropriately.
\n\"Eureka<\/p>\n

Question 3.
\nDraw an acute angle (your choice of degree), a segment with length 3 cm, a point, a circle with radius 1 in., and a vector (your choice of length, i.e., starting point and ending point). Label points and measures (measurements do not need to be precise, but your figure must be labeled correctly). Use your transparency to translate all of the figures you have drawn along the vector. Sketch the images of the translated figures and label them.
\nAnswer:
\nDrawings will vary. Note: Drawing is not to scale.
\n\"Eureka<\/p>\n

Question 4.
\nWhat is the length of the translated segment? How does this length compare to the length of the original segment? Explain.
\nAnswer:
\nThe length is 3 cm. The length is the same as the original because translations preserve the lengths of segments.<\/p>\n

Question 5.
\nWhat is the length of the radius in the translated circle? How does this radius length compare to the radius of the original circle? Explain.
\nAnswer:
\nThe length is 1 in. The length is the same as the original because translations preserve lengths of segments.<\/p>\n

Question 6.
\nWhat is the degree of the translated angle? How does this degree compare to the degree of the original angle? Explain.
\nAnswer:
\nAnswers will vary based on the original size of the angle drawn. The angles will have the same measure because translations preserve degrees of angles.<\/p>\n

Question 7.
\nTranslate point D along vector \\(\\overrightarrow{A B}\\), and label the image D’. What do you notice about the line containing vector \\(\\overrightarrow{A B}\\) and the line containing points D and D’? (Hint: Will the lines ever intersect?)
\n\"Eureka
\nAnswer:
\n\"Eureka
\nThe lines will be parallel.<\/p>\n

Question 8.
\nTranslate point E along vector \\(\\overrightarrow{A B}\\), and label the image E’. What do you notice about the line containing vector \\(\\overrightarrow{A B}\\) and the line containing points E and E’?
\n\"Eureka
\nAnswer:
\n\"Eureka
\nThe lines will coincide.<\/p>\n","protected":false},"excerpt":{"rendered":"
