b: The orientation of the hexagon does not change. a: The orientation of the hexagon does not change. ! 0.0019 No, this probability is very small. a: y =ī: The resulting line coincides with the original line y = c: The image is parallel y =ĭ: They are parallel, because they all have a slope of e: y = ! c: d:Į: The outcomes that satisfy part (d) include the outcomes that satisfy part (c), but there are others on the part (d) list as well. If the outcomes are equally likely, we can use the theoretical probability computation in the Math Notes box in Lesson 1.2.1. a: There are 10 combinations: a & b, a & c, a & d, a & e, b & c, b & d, b & e, c & d, c & e, d & e b: Yes. mAB = mCD = 12 and mBC = mAD = !2, so each pair of consecutive sides is perpendicular and forms 90° angles. a: Reflection b: Translation (or two reflections over parallel lines) c: Rotation or rotation and translation d: Rotation or rotation and translation depending on point of rotation e: Reflection f: Reflection and then translation or rotation or both 1-65. The height of the cylinder would match the height of the rectangle along the pole, and the cylinder’s radius would match the width of the rectangle. While there are an infinite number of rectangles, possible dimensions with integral measurements are: 1 by 24 (perimeter = 50 units), 2 by 12 (perimeter = 28 units), 3 by 8 (perimeter = 22 units), and 4 by 6 (perimeter = 20 units). Perimeter: 74 centimeters, Area: 231 cm 2 1-45. a: Yes, it is correct because the two angles make up a 90° angle.

a: 6x + 6 b: 6x + 6 = 78, so x = 12 and the rectangle is 15 cm by 24 cm. If he left them outdoors, they will still be dead because it has not rained for 2 weeks, so he needed to water them once a week as well. If his plants are indoors, they will be dead because he will be gone for 2 weeks and so he did not water them at least once a week.

No – if the points are collinear then they will not form a triangle. Possible responses include “They have 3 sides of equal length” and “They have 3 angles of equal measure.” 1-16. Possible responses include “How many sides does it have?”, “Does it have a right angle?”, “Are any sides parallel?” 1-15. Possibilities: Goes to bank, gets money from parent, gets paid buys lunch, goes shopping, pays a bill, … Shapes (a), (c), (d), and (e) are rectangles.
