Across
- 4. A set of positive whole number integers a, b, and c that matches the Pythagorean Theorem. Common sets include 3-4-5, 5-12-13, 7-24-25, 8-15-17, 9-40-41
- 6. 90 – the acute angle theta of a right triangle
- 7. The sin, cos, tan functions on a calculator that finds measures of sides in a right triangle
- 9. The square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides
Down
- 1. The angle going downward between the line of sight and the horizontal from a point of observation. The angle of elevation and angle of depression are congruent alternate interior angles.
- 2. The sin−1,cos−1,tan−1 functions on a calculator that finds measures of sides in a right triangle
- 3. The ratio of opposite side of an acute angle theta over the hypotenuse in a right triangle
- 5. The angle going upward between the horizontal and the line of sight from a point of observation
- 6. The ratio of adjacent side of an acute angle theta over the hypotenuse in a right triangle
- 8. The ratio of opposite side over the adjacent side of an acute angle in a right triangle (the ratio of sine θ over cosine θ)
