Basics of Transformation and Translations

Front

What is a transformation in geometry?

Back

A transformation in geometry refers to the movement of a shape in a plane, which can include translations, rotations, reflections, and dilations.

What is a translation?

Back

A translation is a type of transformation that slides a shape from one position to another without turning it or flipping it.

What is a rotation?

Back

A rotation is a transformation that turns a shape around a fixed point, known as the center of rotation, by a certain angle.

What is a reflection?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image of the original shape.

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same, defined by a scale factor.

What does a scale factor greater than one indicate in dilation?

Back

A scale factor greater than one indicates an enlargement of the shape.

What does a scale factor less than one indicate in dilation?

Back

A scale factor less than one indicates a reduction of the shape.

What is the center of rotation?

Back

The center of rotation is the fixed point around which a shape is turned during a rotation.

How do you describe a translation?

Back

A translation can be described by indicating the direction and distance the shape moves, such as '5 units right and 2 units down'.

What is the difference between a translation and a reflection?

Back

A translation slides a shape without changing its orientation, while a reflection flips a shape over a line, changing its orientation.
