1. Additional Topics in Math Lessons 1-2
Using Formulas
Surface Area and Volume of Other Shapes
Computations Involving Angles and Lines
Computations Involving Triangles
Determining Lengths and Angles for Special Right Triangles
Computing Polygon Line Lengths and Angle Measures

2. Using Formulas Be sure to access the test information page
Remember height must be measured vertically
Plug in what you have and solve for the missing piece
Watch your units
Lengths, circumference, etc – ft, cm, in, m
Area – ft2, cm2, in2, m2
Volume – ft3, cm3, in3, m3

3. Surface Area and Volume of Other Shapes
Add multiple shapes together
Find a shape and subtract the missing pieces

4. Computations Involving Angles and Lines
Vertical angles are equal
Straight Lines are 180̊

5. Computations Involving Triangles
Triangles contains 180̊
Isosceles triangles have two equal sides and two equal angles
Isosceles triangles can be cut into two equal halves with an altitude
Equilateral triangles have 3 equal sides and 3 60̊ angles
Right triangles have one right angles and two acute angles that add to 90̊
The Pythagorean Theorem can be used to find missing sides of a right triangle

6. Determining Lengths and Angles for Special Right Triangles
45̊-45̊-90̊ triangles have sides of 1, 1, √2 Or x, x, x√2
30̊-60̊-90̊ triangles have sides of 1, 2, √3 Or x, 2x, x√3
Remember shortest side is opposite smallest angle and longest side is the hypotenuse

7. Computing Polygon Line Lengths and Angle Measures
In a triangle the longest side must be shorter than the sum of the other two sides
The Sum of Exterior Angles (one at each vertex) of a polygon equals 360
The Sum of Interior Angles of a polygon equals 180(n – 2) because you can split the polygon into (n – 2) triangles
Parallel lines make congruent angles and supplementary angles
