Translation, Reflection, Rotation

Front

What is translation in geometry?

Back

A slide of an object from one place to another that preserves size and shape.

Front

When translating LEFT or RIGHT, which axis are you moving on?

Back

X-axis

Front

When translating UP or DOWN, which axis are you moving on?

Back

Y-axis

Front

What is reflection in geometry?

Back

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

Front

State the line of reflection across the y-axis.

Back

Reflection across y-axis.

Front

State the line of reflection across the x-axis.

Back

Reflection across x-axis.

Front

What happens to the coordinates of a point (x, y) when reflected across the x-axis?

Back

The coordinates become (x, -y).

Front

What happens to the coordinates of a point (x, y) when reflected across the y-axis?

Back

The coordinates become (-x, y).

Front

If point X is at (1, 2), where would it be after translating 3 units to the left and 4 units up?

Back

(1-3, 2+4) = (-2, 6).

Front

If point X is at (2, 3), where would it be after translating 5 units to the right and 2 units down?

Back

(2+5, 3-2) = (7, 1).
