Across
- 3. is denoted as, sin^-1; we use it to find the acute angle of a right triangle that has the ratio O/H.
- 4. is denoted as, tan^-1; we use it to find the acute angle of a right triangle that has the ratio O/A.
- 6. if a^2 + b^2 = c^2, where a & b are the legs of a the triangle and c is the hypotenuse, then the triangle is a right triangle.
- 10. the angle made by a line that rises above the horizontal.
- 11. a mathematical expression that has a radical sign/symbol such as a square root (√) or a cube root (∛).
- 12. the trigonometric function that is equal to the ratio of the side opposite to an acute angle to the hypotenuse, in a right triangle.
- 13. these have side lengths relationship: a, a, a√2.
- 14. the trigonometric function that is equal to the ratio of the side opposite to an acute angle to the adjacent side, in a right triangle.
- 15. to find all measures of unknown angles and sides of a right triangle. To do this, you need to know either: 1). Two side lengths, or 2). One side length and one acute angle.
Down
- 1. the trigonometric function that is equal to the ratio of the side adjacent to an acute angle to the hypotenuse, in a right triangle.
- 2. the angle made by a line that falls below the horizontal.
- 5. a ratio that uses two sides of a right triangle in order to find the missing value.
- 7. When an altitude is drawn from the right angle of a triangle, it creates three of these.
- 8. these have side lengths relationship: a, a√3, 2a.
- 9. is denoted as, cos^-1; we use it to find the acute angle of a right triangle that has the ratio A/H.
