Similarity Test Review

Front

What is the definition of similar triangles?

Back

Triangles are similar if their corresponding angles are equal and the lengths of their corresponding sides are proportional.

Front

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.

Front

How do you determine if two triangles are similar?

Back

Two triangles are similar if they satisfy one of the following criteria: AA (Angle-Angle), SSS (Side-Side-Side), or SAS (Side-Angle-Side).

Front

If triangle A has sides of lengths 4, 6, and 8, and triangle B has sides of lengths 2, 3, and 4, are they similar?

Back

Yes, triangle A and triangle B are similar because the ratios of their corresponding sides are equal (1:2).

Front

If two polygons are similar, how do you find the scale factor from the smaller to the larger figure?

Back

Divide the length of a side of the larger figure by the length of the corresponding side of the smaller figure.

Front

What is the relationship between the areas of two similar figures?

Back

The ratio of their areas is the square of the scale factor.
