Study Notes

Composition of Transformations

Involves applying one transformation to a figure and a second transformation to the resultant image.
Used to achieve complex transformations through sequential operations.

Corresponding Parts

Refers to parts of figures that are congruent or similar that correspond to each other.
Essential in establishing the relationship between figures when proving congruence or similarity.

Indirect Measurement

A strategy that employs properties of similar polygons to estimate lengths or distances that are challenging to measure using standard methods.
Useful in various real-world applications, such as surveying and architecture.

Scale Factor

Defined as the ratio comparing the lengths of two corresponding sides of similar polygons.
Critical for understanding the proportional relationships in geometric figures.

Similar Figures

Two figures are considered similar if one can be derived from another through transformations and dilations.
This concept is foundational in geometry for analyzing shape comparison.

Similar Polygons

Polygons that share the same shape but may differ in size.
All corresponding angles are equal, and the lengths of corresponding sides are proportional.
