Theorems and Postulates
- AA (Angle-Angle): If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
- SAS (Side-Angle-Side): If two sides and the included angle of one triangle are proportional to two sides and the included angle of another triangle, then the triangles are similar (ab/de = ac/df).
Shapes
- Opposite angles are always supplementary.
Parallelogram
- Opposite sides are parallel and congruent.
- Opposite angles are congruent.
Understanding Sales Invoices: Key Elements & Regulations

Mastering Essential Math Concepts: Algebra to Statistics
Multiplying Binomials
Multiply (3r – 1)(2r + 3).
Use the FOIL method, keeping the largest exponent on the left. Multiply each number on the left by both numbers on the right.
This gives you 6r2 + 9r – 2r – 3. Combine like terms, 9r – 2r = 7r. This gives you (6r2 + 7r – 3). This is the answer.

1. FSU Volleyball Team: Probability of Losing Both Games
The probability that the FSU volleyball team wins a game is 0.8. If the team has two games this weekend, assuming independence of events, what is the probability that the team will lose both games?
P(A) = (1 – 0.8) = 0.2
P(B) = (1 – 0.8) = 0.2
P(losing both games) = 0.2 x 0.2 = 0.04
