DOUBLE
Are these figures similar? How do you know?
Yes, the ratios of the sides are proportional
What is true about the ratio of the perimeters of similar figues?
The ratio will be the same as the ratio of the sides
Is this a translation? If not, what is it?
YES!
DOUBLE!!! Is this a reflection? If not, what is it?
No! (Rotation!)
No
What is true about the ratio of the areas of similar figures?
The ratio will be the same as the SQUARE of the ratio of the sides
