Unformatted text preview: MAT 157-CheckPoint Template Name: Week #: 5 Instructions: For each assigned problem type in the page number, problem number, and complete solution, showing all work for each problem (using either MathType or Equation Editor recommended) in order to receive credit. One problem in each row, please. Page # Prob # Complete Solution 669 8 The orientation of the figure did not change so it couldn’t have been a reflection or glide reflection. A translation of the corner showing the square to its image would not translate the other corners to their images so it can’t be a translation. So it must be a rotation. 10 A translation. 24 (a) 45° rotational symmetry (b) 90° rotational symmetry (c) 15° rotational symmetry (d) 180° rotational symmetry, or point symmetry (e) No rotational symmetry (I considered color) (f) 72° rotational symmetry 672 38 a.) b.) c.) d.) e.) f.) g.) h.) 686 4 4 rectangles because the sum of all the joining angles around the pivot point is 360 degrees. Therefore it would take 4 corners at 90 pivot point is 360 degrees....
