  1. 4. The angle formed by the horizontal line of sight and the line of sight looking up to an object.
  2. 6. A special right triangle that has congruent legs. Since the legs are congruent, the angles opposite the legs are also congruent.
  3. 9. Ratios that express the relationship between a right triangle's side lengths and its interior angles.
  4. 14. The angle formed by the horizontal line of sight and the line of sight looking down to an object.
  5. 15. A special right triangle with angles in the ratio 1:2:3.
Down
  1. 1. The ratio of the side opposite an angle to the hypotenuse in a right triangle.
  2. 2. For two positive numbers a and b, this is the positive number x such that a/x = x/b (or x = ab).
  3. 3. A relationship between the sides and angles of non-right (oblique) triangles. It relates the lengths of the sides of a triangle to the cosine of one of its angles, often used to find missing side lengths or angles when the Law of Sines is not directly applicable.
  4. 5. The relationship between angles and their opposite sides of non-right (oblique) triangles. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides and angles.
  5. 7. The two sides of a right triangle that form the right angle.
  6. 8. The longest side of a right triangle and opposite the right angle.
  7. 10. The ratio of the side opposite an angle to the side adjacent to the angle in a right triangle.
  8. 11. The ratio of the side adjacent to an angle to the hypotenuse in a right triangle.
  9. 12. The measurement of triangles. It explores the mathematical relationships between the side lengths and interior angles of triangles.
  10. 13. A theorem that relates the lengths of the sides of a right triangle.
