Translation & Reflection

Front

State the line of reflection for the point (2, 3) reflected over the line y = 1.

Back

The line of reflection is y = 1.

Front

Reflect Point A (4, 5) over the y-axis. What are the coordinates of the reflected point?

Back

The reflected point is (-4, 5).

Front

A slide in geometry is also called a _________.

Back

Translation.

Front

What do we call the original figure before a transformation occurs?

Back

Pre-image.

Front

What is the Algebraic Notation for reflecting a point over the y-axis?

Back

(x, y) → (-x, y).

Front

What is the result of reflecting the point (3, -2) over the x-axis?

Back

The reflected point is (3, 2).

Front

Define 'Translation' in geometry.

Back

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

Front

What is the effect of reflecting a point over the line y = x?

Back

The coordinates of the point (x, y) become (y, x).

Front

If the point (5, 7) is reflected over the line y = -1, what are the new coordinates?

Back

The new coordinates are (5, -9).

Front

What is the difference between a reflection and a rotation?

Back

A reflection flips a figure over a line, while a rotation turns a figure around a point.
