| Term | Definition |
| Term | A Product of Numbers and Variables. |
| Polynomial | Any Amount of Terms Being Multiplied Together. |
| Monomial | A Single Term Consisting of a Number and Variable. |
| Binomial | Two Terms, Consisting of Numbers and Variables, that are Multiplied Together. |
| Trinomial | Three Terms, Consisting of Numbers and Variables, that are Multiplied Together. |
| Parallel Lines | A Pair of Lines, that are, an Equal Distance away from Each Other, That Goes On Forever, Without Intersecting. |
| Transversal | A Line Cutting Throught a Pair of Parallel Lines. |
| Complementary Angle | An Angle Measuring 90 Degrees. |
| Supplementary Angle | An Angle Measuring 180 Degrees. |
| Straight Line | A Straight Line Measuring 180 Degrees. |
| Vertical Angle | Two Intersecting Lines That have opposite angles- One Angle Equals Its Opposite- A = B, C= D. The Two Angles Adjacent to Each Other, and are not Opoposite, to Each Other, add up to 180 Degrees, because it forms a Straight Line. |
| Adjacent Angle | Two Angles That Share A Common Side. |
| Alternating Interior Angle | In a Transversal, two opposite sides that equal each other inside the Transversal, are Alternating Interior Angles. |
| Alternating Exterior Angle | In a Transversal, two opposite sides that equal each other outside the Transversal, are Alternating Exterior Angles. |
| Pythagorean Theorem | A Method of Finding out if the triangle is a Right Triangle, by using the Formula, and that When the two shorter legs, squared, are added up, it equals the Hypotenuse, squared, while the Hypotenuse is always larger than Leg A and Leg B. |
| Pythagorean Theorem Formula | The Pythagorean Theorem Formula, is A² + B² = C², meaning Leg A Squared + Leg B Squared = Hypotenuse Squared. |
| Pythagorean Triplets | When A, B, and C, meaning, Leg A, Leg B, or the Hypotenuse has a consecutive pattern, then It's called, Pythagorean Triplets. |
| F. O. I. L. | A Method of multiplying two binomials, by multiplying in the order: F- First (First Term in each Binomial.), O- Outer (The First Term in the First Binomial and the Last Term in the Second Binomial.), I- Inner (The Last Term in the First Binomial, and the First Term in the Second Binomial.), and L- Last. (The Last Term in Each Binomial.) |
| Right Triangle | A Triangle that has a Right Angle, Measuring 90 Degrees. |
| Right Angle | The Right Angle Measures 90 Degrees. |
