Trigonometry Vocab Puzzle
Across
- 4. A triangle in which two sides are perpendicular, forming a right angle.
- 6. Define three functions (cosecant, secant, cotangent) as the inverse fractions (reciprocals) of the other three fundamental functions (sine, cosine, tangent), allowing for simplification and solving equations.
- 9. Angle: Any angle that is not a right angle 90° or a multiple of a right angle.
- 10. Angle: any angle in standard position (vertex at origin, initial side on positive x-axis) whose terminal side does not lie on the x-axis or y-axis
- 12. Relationships where a trigonometric function of an angle equals another function (its "co"-function) of that angle's complement.
- 14. A triangle where all three of its interior angles are less than 90 degrees.
- 15. A unit for measuring angles, defined as the angle at the center of a circle that subtends an arc whose length is equal to the circle's radius.
- 16. An angle that is exactly half of another angle.
- 17. Those numbers that follow each other in increasing order from smallest to largest with no missing numbers in between.
- 18. The average between the maximum and minimum value.
- 19. Two angles whose measures add up to exactly 180°.
- 20. The smallest positive, acute angle formed between the terminal side of an angle 𝜃 and the horizontal x-axis, always resulting in a value between 0° and 90°.
Down
- 1. The process of breaking down complex trigonometric expressions or equations into simpler products (factors) of trigonometric functions.
- 2. The corner point where two lines or rays meet to form an angle.
- 3. The quarter increments of the period.
- 5. The horizontal length at a cycle.
- 7. The ‘’undo’’ functions for sine, cosine, and tangent, taking a side ratio as input and returning the corresponding angle.
- 8. Two acute angles that sum up to 90 degrees, forming a right angle.
- 11. Equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined.
- 13. The distance between two points along a curve.
