column a

1. sphere
2. cylinder
3. reflection
4. translation
5. rigid transformations
6. line of reflection
7. rotation
8. prime notation
9. mapped
10. parallel
11. perpendicular
12. equidistant

column b
a. a line that divides a shape into two congruent parts that are mirror images of each other
b. a transformation that preserves the size, shape, and orientation of a figure while sliding (moving) it to a new location
c. a three - dimensional figure that consists of two parallel congruent circular regions (called bases) and a lateral surface containing segments connecting each point on the circular boundary of one base to the corresponding point on the circular boundary of the other
d. movements of figures that preserve their shape and size
e. using a single tick mark (), called a prime, to denote a derivative, a related object, or a similar entity
f. the shape of a basketball
g. line or line segments that have a constant distance between them and never intersect
h. at equal distances.
i. a transformation across a line that produces a mirror image of the original shape
j. a transformation that turns all of the points in the original figure the same number of degrees around a fixed center point (such as the origin on a graph)
k. how an object, like a point on a graph, is moved or transformed from one location to another
l. two rays, line segments, or lines that meet (intersect) to form a right angle (90°)

Explanation:

1. A sphere is a three - dimensional shape like a basketball, so sphere matches with f.
2. A cylinder has two parallel congruent circular bases and a lateral surface, so cylinder matches with c.
3. A reflection is a transformation across a line that produces a mirror image, so reflection matches with i.
4. A translation is a transformation that preserves size, shape and orientation while sliding a figure, so translation matches with b.
5. Rigid transformations preserve the shape and size of figures, so rigid transformations match with d.
6. The line of reflection divides a shape into two congruent parts that are mirror images, so line of reflection matches with a.
7. A rotation turns all points in the original figure the same number of degrees around a fixed center point, so rotation matches with j.
8. Prime notation uses a single tick mark to denote a derivative or related object, so prime notation matches with e.
9. Mapped refers to how an object is moved or transformed from one location to another, so mapped matches with k.
10. Parallel lines or line - segments have a constant distance between them and never intersect, so parallel matches with g.
11. Perpendicular lines or segments meet at a right angle, so perpendicular matches with l.
12. Equidistant means at equal distances, so equidistant matches with h.

Answer:

1. f
2. c
3. i
4. b
5. d
6. a
7. j
8. e
9. k
10. g
11. l
12. h
