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

• (x, y) goes to (1/3x, 1/3y)

• (x, y) goes to (-3x, -3y)

• (x, y) goes to (x + 3, y + 3)

• (x, y) goes to (3x, 3y)

What is a dilation?

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

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

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

CCSS.8.G.A.3

A transformation that makes an object larger or smaller by a scale factor of the original.

When are figures similar?

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

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

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

What is a scale factor?

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

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

• A variable to consider when weighing an item
