What is the ratio of sides for a 45–45–90 triangle? | x : x : x√2 |
What is the ratio of sides for a 30–60–90 triangle? | short leg : long leg: hypotenuse y : y √3 : 2y |
What are the three recommended pythagorean triples to remember? | 3 : 4 : 5 5 : 12 : 13 7 : 24 : 25 |
What is the ratio for Sine? | opposite side to focused angle / hypotenuse |
What is the ratio for Cosine? | adjacent side to focused angle / hypotenuse |
What is the ratio for Tangent? | opposite side to focused angle / adjacent side to focused angle |
What is a conjugate? | This is the term used to remove radicals in the denominator when the denominator is represented with an irrational binomial. Example: if the denominator has (3–√5), then one would multiply both the numerator and denominator by (3+√5). |
