Key Takeaways


  • If there are multiple triangles in one diagram you can assume they are similar triangles with congruent corresponding angles and proportional corresponding sides
  • The SAT likes to include ratios and isosceles triangles as hidden concepts that are helpful in solving these problems
  • The exterior angle theorem is not necessary, but it can be helpful as a shortcut
  • It is often helpful to think about what piece of information would get you one step from the answer and then to work towards finding that
