Answer

1/2

Question 2

How do you write the algebraic notation when the scale factor is 3?

Accepted Answer

(x, y) goes to (3x, 3y)

Answer

(x, y) goes to (1/3x, 1/3y)

Answer

(x, y) goes to (-3x, -3y)

Answer

(x, y) goes to (x + 3, y + 3)

Question 3

A dilation produces a similar figure

Accepted Answer

True

Answer

False

Question 4

How many degrees was the figure rotated?

Accepted Answer

180 degrees

Answer

90 degrees counterclockwise

Answer

270 counterclockwise

Answer

90 degrees clockwise

Question 5

What is a dilation?

Accepted Answer

a transformation in which each point on a figure moves along a line and changes its distance from a fixed point

Answer

we multiply all the lengths in the original figure by the same number

Answer

a fixed point on a plane and is the starting point from which we measure distances in a dilation

Question 6

When are figures similar?

Accepted Answer

if one can fit exactly over the other after rigid transformations and dilations

Answer

When we multiply all the lengths in the original figure by the same number

Answer

a transformation in which each point on a figure moves along a line and changes its distance from a fixed point

Question 7

What is a scale factor?

Accepted Answer

The number used to multiply all the lengths in the original figure by the same number

Answer

a fixed point on a plane and is the starting point from which we measure distances in a dilation

Answer

A variable to consider when weighing an item
