What to Focus On
- Similar figures have the same shape, not necessarily the same size.
- For polygons, both equal angles and proportional sides are needed.
- Scale factor and Representative Fraction mean the same thing.
- BPT is also called the Thales Theorem.
- A parallel line inside a triangle divides the two sides proportionally.
- The converse of BPT helps prove parallelism.
- AAA, AA, SSS, and SAS are the main similarity criteria for triangles.
- Equal angles lead to similarity by AAA or AA.
- Proportional sides lead to similarity by SSS.
Common Mistakes to Avoid
Similar triangles are the same as congruent triangles.
For triangles, both equal angles and equal side ratios must always be checked separately.
Vertex order does not matter in similarity notation.
