8th math Transformations

Front

What is a transformation in geometry?

Back

A transformation in geometry refers to the movement of a shape on a graph, which can include turning, flipping, or sliding the shape.

What happens to a shape during a dilation with a scale factor less than one?

Back

The shape undergoes a reduction, making it smaller.

Front

What is the result of a dilation?

Back

A dilation produces a similar figure, maintaining the shape's proportions but changing its size.

What is the scale factor in a dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation.

What is the difference between a rotation and a reflection?

Back

A rotation turns a shape around a fixed point, while a reflection flips it over a line.

Can a transformation change the size of a shape?

Back

Yes, transformations like dilation can change the size of a shape, while translations and reflections do not.

What is the effect of a scale factor greater than one in a dilation?

Back

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

What is the line of reflection?

Back

The line of reflection is the line over which a shape is flipped to create its mirror image.
