- 4. A fundamental relation in geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
- 7. A unit of measure for angles. One complete revolution is 2π radians.
- 8. In a right triangle, the ratio of the length of the opposite side to the length of the adjacent side.
- 10. A unit of measurement for angles. One complete revolution is 360 degrees.
- 11. The longest side of a right-angled triangle, opposite the right angle.
- 12. The reciprocal of sine.
- 13. A mnemonic used to remember the definitions of sine, cosine, and tangent: Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent.
- 14. In relation to a given angle in a right triangle, the side that is furthest from the angle.
Down
- 1. A branch of mathematics that studies relationships involving lengths and angles of triangles.
- 2. A triangle with one angle measuring 90 degrees.
- 3. The reciprocal of tangent.
- 5. In a right triangle, the ratio of the length of the side that is adjacent to the angle to the length of the hypotenuse.
- 6. In relation to a given angle in a right triangle, the side that is next to the angle.
- 9. The reciprocal of cosine.
- 13. In a right triangle, the ratio of the length of the side that is opposite the angle to the length of the longest side, the hypotenuse.
