What to know for the Chapter 9 Test
Definitions
 Pythagorean Triples (you need to know 5 familes!)
 Prism parts: faces, edges, diagonals
 Pyramid parts: base, vertex, altitude, slant height
 Cube
 Sine, Cosine, Tangent (remember SOHCAHTOA)
Theorems
 AltitudeonHypotenuse Theorems (there are three relationships to know here!)
 The Pythagorean Theorem and it's converse
 The Distance Formula
 Isosceles Right Triangle Theorem
 3060 Right Triangle Theorem
Types of Problems
 Simplifying square roots (including reducing, adding, subtracting, multiplying, and dividing)
 AltitudeonHypotenuse 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.)
 Solving for lengths using the Distance Formula
 Using Pythagorean Triples to solve right triangle problems
 Using special right triangles to solve related problems
 Solving problems involving right triangles in prisms and pyramids
 Determining the trigonometric ratios (Sine, Cosine, and Tangent) based on the side lengths of right triangles
 Using the inverse trigonometric function keys on a calculator (or reading from the trig table) to determine angle measurements of a triangle given side lengths
