Across
  1. 2. A special right triangle that has a side ratio of 1:1:√2 (hint: it is isosceles)
  2. 6. A special right triangle that has a side ratio of 1:√3:2
  3. 9. Adjacent side/ Hypotenuse
  4. 11. The longest side in a right triangle
  5. 12. The side opposite to a specific angle
  6. 14. Leg^2+Leg^2=Hypotenuse^2 (hint: used to find the measure of one side of a right triangle)
  7. 17. the angle formed by the horizontal and the line of sight when looking downward
  8. 19. A line dropping from the vertex to another line through the use of a perpendicular bisector
  9. 20. A triangle with one angle measuring 90 degrees
Down
  1. 1. Law used to find the values of sides and angles in triangles. Sin A/a = Sin B/b = Sin C/c
  2. 3. The study of right triangles
  3. 4. An angle equal to 90 degrees
  4. 5. The imaginary line drawn from the eye of the observer to the object
  5. 7. the angle formed by the horizontal and the line of sight when looking upward
  6. 8. A side that shares a vertex with another side
  7. 10. Opposite side/Hypotenuse
  8. 13. Another law used to find the values of sides and angles in triangles. c2 = a2 + b2 − 2ab cos(C)
  9. 15. In a right triangle, the length of the altitude (x) squared is equal to the two segments created on the line it is projected to (a and b) multiplied. (x^2=ab)
  10. 16. The sides of a right triangle not including the hypotenuse
  11. 18. Opposite side/ Adjacent side
