Understanding Dilations in Geometry

Front

What is dilation in geometry?

Back

A transformation that changes the size of a geometric figure but does not change its shape.

Front

What does the dilation math definition indicate?

Back

The shape of the figure will not change, but the length of each individual side will change in a proportional manner.

Front

What are similar figures?

Back

Figures that are the same shape but different sizes, having many of the same properties but not identical.

Front

Give an example of similar figures.

Back

The Sun and Moon might appear the same size but are actually different in size.

Front

What properties are preserved in a dilation?

Back

Angle measure, parallelism, and collinearity are preserved.

Front

What property is not preserved in a dilation?

Back

Distance is not preserved, but it is proportional.

Front

What is the main focus of studying dilations?

Back

Understanding that distance is not preserved but is proportional.
