Translation, Reflection, Rotation

Front

What is Translation in geometry?

Back

Translation is a type of transformation that moves every point of a shape a certain distance in a specified direction.

Front

What does it mean to Reflect a shape?

Back

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

Front

What is Rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point, called the center of rotation, by a certain angle.

Front

How do you describe a Translation?

Back

A translation can be described by the direction and distance moved, such as 'right 3 units and down 2 units'.

Front

What is the result of reflecting a shape over the x-axis?

Back

The y-coordinates of the points of the shape change sign, while the x-coordinates remain the same.

Front

What happens to a shape during a 90° clockwise Rotation?

Back

The coordinates of each point of the shape are transformed according to the rule (x, y) -> (y, -x).

Front

What is the difference between Translation and Reflection?

Back

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

Front

If a shape is translated 5 units left and 3 units up, what is the new position of a point (2, 1)?

Back

The new position will be (-3, 4).

Front

What is the angle of Rotation for a full turn?

Back

The angle of rotation for a full turn is 360°.

Front

How can you identify a Reflection transformation?

Back

A reflection can be identified by the symmetry of the shape across a line, where corresponding points are equidistant from the line.
