Translations & Coordinate Plane Flashcard

Front

What is a translation in geometry?

Back

A transformation that moves a figure to a new location without changing its size, shape, or orientation.

Front

What are the properties of a translation?

Back

1. Same Shape 2. Same Size 3. Different Location

Front

Which of the following is NOT a property of translation? Images are facing opposite, Same Shape, Same Size, Different Location.

Back

Images are facing opposite.

Front

How do you translate a point (x, y) 3 units left and 9 units down?

Back

Subtract 3 from x and 9 from y: (x-3, y-9).

Front

If point X is at (1, 4), where is X' after translating 3 units left and 9 units down?

Back

X' is at (-2, -5).

Front

What does it mean for two points to be on the same vertical line?

Back

They have the same x-coordinate.

Front

What does it mean for two points to be on the same horizontal line?

Back

They have the same y-coordinate.

Front

What is the result of translating point (7, -3) 0 units left and 17 units up?

Back

The new point is (7, 14).

Front

What is the difference between translation and reflection?

Back

Translation moves a figure without changing its orientation, while reflection flips it over a line.

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).
