Day 7

Spaced Revision

Come back to Pythagoras Theorem after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • The hypotenuse is the side opposite the right angle.
  • Use PR^2 = PQ^2 + QR^2 in triangle PQR with angle PQR = 90 degrees.
  • In side-letter form, q^2 = p^2 + r^2.
  • A Pythagorean triplet has one number whose square equals the sum of squares of the other two.
  • The order of the numbers does not matter.
  • The formula [(a^2 + b^2), (a^2 - b^2), (2ab)] works only when a > b.
  • In a 30-60-90 triangle, the side opposite 30 degrees is half the hypotenuse.
  • In the same triangle, the side opposite 60 degrees is (sqrt(3)/2) times the hypotenuse.
  • In a 45-45-90 triangle, both legs are equal.

Common Mistakes to Avoid

Any triangle can be solved using Pythagoras theorem.

The longest side in a triangle is always the hypotenuse.

Pythagoras theorem and its converse mean the same thing.
