Exploring Similarity and Transformations in Geometry

What is the key concept to determine if two figures are similar?

• The figures must be identical.

• The figures must have the same color.

• The figures must be in the same position.

• The figures must have the same ratio between their sides.

In the first example, what is the ratio of side EF to side VW?

• 1/2

• 2/3

• 3/2

• 3/4

Why is it important to compare different sets of sides when determining similarity?

• To confirm the figures have the same color.

• To check if the figures are in the same orientation.

• To verify that the ratios are consistent across all corresponding sides.

• To ensure the figures are the same size.
