Trigonometry Vocab Puzzle

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°.

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.
