  1. 2. triangle a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist
  2. 4. the quantitative relation between two amounts showing the number of times one value contains or is contained within the other
  3. 6. Theorem is a fundamental relation in Euclidean 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
  4. 8. A relationship or expression involving one or more variables
  5. 12. SOHCAHTOA
  6. 14. The branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles
  7. 15. Special triangle with three different angles
  8. 16. a unit of measurement of angles
  9. 17. a process in which a number, quantity, expression, etc., is altered or manipulated according to formal rules, such as those of addition, multiplication, and differentiation
  10. 19. Opposite of tangent; Cosine over sine
  11. 20. Opposite of cosine; Hypotenuse over adjacent
  12. 21. Opposite over Hypotenuse
