TRANSFORMATIONS - REVIEW

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape.

Front

Define translation in geometry.

Back

Translation is a type of transformation that slides a shape a certain distance in a specified direction.

Front

What does the notation (x, y) --> (x + a, y + b) represent?

Back

It represents a translation of a point (x, y) by 'a' units horizontally and 'b' units vertically.

Front

What is the effect of a translation of 4 squares right and 5 squares down on a point (2, 3)?

Back

The new point will be (2 + 4, 3 - 5) = (6, -2).

Front

What is reflection in geometry?

Back

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

Front

What is the line of reflection?

Back

The line of reflection is the line over which a shape is reflected to create 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.

Front

What does a scale factor of 2 mean in dilation?

Back

A scale factor of 2 means that the shape is enlarged to twice its original size.

Front

How do you identify a translation on a graph?

Back

A translation can be identified by observing that all points of the shape move the same distance in the same direction.

Front

What is the difference between translation and reflection?

Back

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