Geo 3.1-3.2 Reflection and Translation write the rule-Flashcard

Front

What is the line of reflection for the point (4, 9) reflected across the x-axis?

Back

Reflection across x-axis.

Front

If a point (4, 9) is transformed using the rule (x + 1, y - 3), what is the new point?

Back

(5, 6)

Front

What is the image of point Q (1, -2) if it is reflected over the line y=x, then reflected over the x-axis?

Back

(1, 2)

Front

Which triangle is a translation of triangle X?

Back

Triangle B.

Front

Is the reflection shown a reflection over the x or y axis if the original point is (3, 4) and the reflected point is (3, -4)?

Back

x axis.

Front

Define reflection in geometry.

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

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

Back

(x, -y).

Front

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

Back

(-x, y).

Front

What is the rule for reflecting a point (x, y) over the line y=x?

Back

(y, x).

Front

What is translation in geometry?

Back

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