1. What is a proportion?
A proportion is an equation that states that two ratios are equal. It expresses the relationship between two quantities.
2. Explain what it means for two figures to be similar.
Two figures are similar if they have the same shape, but may have different sizes. The corresponding angles of the figures are equal, and the corresponding side lengths are in proportion.
3. What is a scale factor?
A scale factor is the ratio of the lengths of corresponding sides of two similar figures. It determines how much one figure is magnified or reduced to create the other figure.
4. How can you determine if two polygons are similar?
Two polygons are similar if their corresponding angles are congruent and their corresponding side lengths are proportional.
5. What is the relationship between the ratios of corresponding sides in similar figures?
The ratios of corresponding sides in similar figures are equal. This means that the lengths of the corresponding sides can be written in proportion.
