What is a similarity statement in geometry?

Back

A similarity statement indicates that two figures are similar, meaning they have the same shape but may differ in size. It is typically written using the symbol '~', for example, ΔYZX~ΔNWE.

What is the scale factor in similar figures?

Back

The scale factor is the ratio of the lengths of corresponding sides of two similar figures. It indicates how much one figure has been enlarged or reduced compared to the other.
