What to know for the Chapter 9 Quiz


  • I've decided to not test you on any of the circle stuff we did in Section 9-2 since we'll be spending a whole chapter (Chapter 10) on circles later this year!


  • Altitude-on-Hypotenuse Theorems (there are three relationships to know here!)
  • The Pythagorean Theorem and it's converse

Types of Problems

  • Simplifying square roots (including reducing, adding, subtracting, multiplying, and dividing)
  • Altitude-on-Hypotenuse problems (finding side/altitude lengths and/or perimeters)
  • Classifying triangles (acute, right, obtuse and scalene, isosceles, equilateral)
  • Pythagorean Theorem problems (finding side lengths/perimeters/etc.)
