What to Focus On

  • A right triangle has one angle equal to 90 degrees.
  • Solving means finding all remaining sides and angles.
  • One side and one acute angle are enough to begin solving.

  • Solve each right triangle one by one.
  • Use the correct ratio in each triangle.
  • Check whether the required side is made of two segments.

  • Diagonals of a rhombus bisect each other at right angles.
  • Diagonals also bisect the vertex angles.
  • Half of each diagonal is found first.

Common Mistakes to Avoid

Rationalization is only a fancy algebra step and can be skipped after finding the expression.
