  1. 2. the process of reading that a rule or statement is true because specific cases are true
  2. 4. a transformation in which the lines connecting every point P with its preimage p' all intersect at a point C known as the center of the dilation and Cp'/Cp is the same for every point p; a transformation that changes the side of a figure but not it's shape
  3. 5. a transformation about a point P, also known as the center of rotation such that each point and its images are the same distance from P. all of the angles with vertex P formed by a point and its image are congruent
  4. 6. a closed plane figure formed by three or more segments such that each segment intersects exactly two other segments only at their endpoints and no two segments with a common endpoint are collinear
  5. 12. the part of a conditional statement following the word if
  6. 13. having the same size and shape
  7. 14. a statement that describes a mathematical object and can be written as a true biconditional statement
  8. 15. the statement formed by exchanging the hypothesis and conclusion of a conditional statement
  9. 16. the point that divides a segment into two congruent segments
  10. 18. a quadrilateral with four congruent sides and four right angles
  11. 21. the sum of the side lengths of a closed plane figure
  12. 22. a statement that is accepted as truth without proof also called axiom
  13. 23. a line that intersects two coplanar two different points
  14. 25. for two lines intersected by a transversal, a pair of angles that lie on the same side of the transversal
  15. 26. a statement that can be written in the form p if and only if q
  16. 28. the process of using logic to draw conclusions
  17. 29. the part of a conditional statement following the word then
Down
  1. 1. a proof in which the statement to be proved is assumed to be false and a contradiction is shown
  2. 3. a quadrilateral with four congruent sides
  3. 5. a transformation across the line called the line of reflection such that the line of reflection is the perpendicular bisector of each segment joining each point and its image
  4. 7. an angle that measures greater than 90 and less than 180
  5. 8. a statement that is accepted as true without proof
  6. 9. an angle that measures greater than zero nad less than 90
  7. 10. two angles in the same plane with a common vertex and a common side but no common interior points
  8. 11. a quadrilateral with four right angles
  9. 17. a part of a line that starts at an endpoint and extends forever in one direction
  10. 19. the set of points in a plane that are a fixed distance from a given point called the center of the circle
  11. 20. the statement formed by negating the hypothesis and conclusion of a conditional statement
  12. 24. a ray that divides an angle into two congruent angles
  13. 27. to divide into two congruent parts
