Question 1

transformation

Answer 1

moves or changes a figure will make

Question 2

image

Answer 2

transformed figure. P becomes P’

Question 3

isometry

Answer 3

a congruent transformation.

Question 4

translation

Answer 4

an isometry that moves every point in a certain distance in a certain direction.

Question 5

the arrows on the side of a translation mean

Answer 5

those 2 sides are parallel

Question 6

motion rule

Answer 6

moves each point L, R, D, U.

Question 7

rotation

Answer 7

transformation that turns a figure about a fixed point

Question 8

glide reflection

Answer 8

a transformation w/a translation and reflection in the same problem (slide/flip)

Question 9

composition of transformations

Answer 9

any 2 transformations combined to form a single transformation

Question 10

line of symmetry

Answer 10

the figure can be mapped onto itself by a reflection in the line

Question 11

rotational symmetry

Answer 11

the figure can be mapped onto itself by a rotation of 180* or less around a point.
