Similar Triangles (VCE SSCE General Mathematics): Flashcards

Same shape, different sizes, equal angles, proportional sides

Two pairs of matching angles are equal

Only two (third must equal as angles sum to $180°$)

All three pairs of sides have same ratio

Constant ratio between corresponding sides

Two side pairs same ratio + included angle equal

Angle between the two sides being compared

Equal angle must be between compared sides

Only one of the three tests (AA, SSS, or SAS)

AA (Angle-Angle), SSS (Side-Side-Side), SAS (Side-Angle-Side)
