Across
  1. 2. basically indirect proof but reworded. the answer is in indirect proof's definition
  2. 5. an angle whose vertix is on a circle and whose sides contain chords of a circle
  3. 8. in a proportion such that a/b = c/d, b and c are the means
  4. 12. the arc formed by an inscribed angle
  5. 16. a statement that two ratios are equal
  6. 18. the process of reasoning that begins with a true hypothesis and builds a logical argument to show that a conclusion is true
  7. 19. an ordered pair of numbers a and b, written a / b where b does not equal 0.
  8. 20. a line that is in the same plane as a circle and intersects the citcel at exactly one point
Down
  1. 1. a line that intersects a circle at two points
  2. 3. a statement that indicates that 2 polygons are similar by listing the vertices in the order of correspondence
  3. 4. either of the two products obtained by multiplying the two means or the two extremes of a proportion(Vector Product)
  4. 6. a segment whose endpoints lie on a circle
  5. 7. the values of the proportion that are furthest apart when written in ratio form using a colon
  6. 9. the point of intersection of a circle or sphere with a tangent line or plane
  7. 10. a proof in which the statement to be proven is assumed to be false and a contradiction is shown
  8. 11. Two polygons are similar if their corresponding angles are congruent and the corresponding sides have a constant ratio
  9. 13. the length of the perpendicular segment from the point to the line
  10. 14. a style of proof that use coordinate geometry and algebra
  11. 15. when 2 objects have the same shape, or one has the same shape as the mirror image of the other.
  12. 17. the ratio of 2 corresponding linear measurements in a pair of similar figures
