Geometry Name Unit 4 Date Lesson 6 Homework Period Tamika drew AFGH on graph paper. She then rotated the graph paper and moved it to the right. H 1. Explain what method(s) can be used to determine if each side of AFGHh same length as the triangle that has been rotated and moved. 2. Explain what method(s) can be used to determine if each angle of AFGHh same measure as the triangle that has been rotated and moved. 3. Explain why showing that the side lengths and the angles have the same measure shows that the transformations used can be classified as isometry. Line segments TN, T'N', and point A are shown on the grid. 4 Draw ZTAT'. Label the angle measure. 5. Describe the transformation applied to TN A that resulted in T'N'. N' 6. Complete the statement. N There is a between the set of points on TN and the set of points on T'N', therefore all of the points on have to have a matching point onQuadrilaterals BWRY, B'W'R'Y', and B"W"R"Y" are shown on the coordinate grid.

Describe what movements should be done with a patty paper copy of quadrilateral BWRY so that the copy of BWRY lays on top of B'W'R'Y'. 8. Describe what movements should be done with a patty paper copy of quadrilateral B'W'R'Y' so that the copy of B'W'R'Y" lays on top of B"W"R"Y". 9. Complete the statements. The transformations used in both sequences are are not B'W'R'Y' examples of isometry. All of the points of O B"W"RUY"' o B'W'R'Y' and B"W"R"Y' can be mapped to all of the points of BWRY. 10. Use the definition of congruence in terms of rigid motions to explain how both sequences of transformations for quadrilateral BWRY resulted in BWRY = B"W"R"Y"
