Transformations Flashcard

Front

What happens when you translate a shape?

Back

You add or subtract a number to the x and y coordinates.

Front

What is the algebraic notation for translating a figure 6 units right and 5 units up?

Back

(x, y) --> (x + 6, y + 5)

Front

What is the term for flipping a shape over an axis or line?

Back

Reflection

Front

What is the result of rotating a triangle 90° clockwise around the origin?

Back

The triangle's position changes based on the rotation.

Front

What is a transformation that moves a shape without changing its size or orientation?

Back

Translation

Front

What is the difference between rotation and reflection?

Back

Rotation turns a shape around a point, while reflection flips it over a line.

Front

What is the algebraic notation for reflecting a point (x, y) over the x-axis?

Back

(x, y) --> (x, -y)

Front

What is the algebraic notation for reflecting a point (x, y) over the y-axis?

Back

(x, y) --> (-x, y)

Front

What is the term for a transformation that enlarges or reduces a shape?

Back

Dilation

Front

What is the effect of a 180° rotation on a point (x, y)?

Back

(x, y) --> (-x, -y)
