| Word | Definition |
|---|---|
| Pythagorean Triple | a set of positive integers that satisfy the equation, a^2+b^2=c^2 |
| Trigonomic Ratio | The ratio of two lengths of two sides in a right triangle. |
| Tangent | The ratio of the lengths of the legs in a right triangle. |
| Sine | Trigonomic ratio for acute angles that involves the lengths of the hypotonuse of a right triangle. |
| Cosine | Trigonomic ratio for acute angles that involves the lengths of the hypotonuse of a right triangle. |
| Angle of Elevation | If you look up at an object, the angle your line of sight makes with a horizontal line. |
| Angle of Depression | If you look down at an object, the angle your line of sight makes with a horizontal line. |
| Solve a Right Triangle | to find the measures of all angles and sides. |
| Inverse of Tangent | an inverse tangent ratio, abbreviated as tan^-1. For acute angle A, if tan A = x, then tan^-1(x) = m angleA |
| Inverse of Cosine | an inverse tangent ratio, abbreviated as cos^-1. For acute angle A, if cos(A)=Z, then cos^-1(z) = m angle A. |
| Inverse of Sine | An inverse trigonomic ratio, abbreviated as sin^-1. For acute acute angle A, if A = y, then sin^-1(y) = m angle A. |
