Transformations Geometry

Front

Reflections over the x-axis change the ____-__________.

Back

y-coordinate

Front

Write a rule for the translation that moves a point 2 units to the right and 1 unit down.

Back

(x +2, y - 1)

Front

Identify the transformation: A point is flipped over the x-axis.

Back

Reflection across x-axis

Front

Write a rule for the translation that moves a point 1 unit to the left and 2 units up.

Back

(x - 1, y + 2)

Front

Which answer shows a reflection across the x-axis?

Back

c

Front

What is the effect of a reflection over the y-axis on the coordinates of a point (x, y)?

Back

The new coordinates will be (-x, y).

Front

Define translation in geometry.

Back

A transformation that moves every point of a figure the same distance in the same direction.

Front

What is the rule for a 180-degree rotation about the origin?

Back

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

Front

Identify the transformation: A point is moved 3 units to the left and 4 units up.

Back

Translation (x - 3, y + 4)

Front

What happens to the coordinates of a point (x, y) during a reflection over the y-axis?

Back

The new coordinates will be (-x, y).
