Across
  1. 1. A figure that has one endpoint and extends infinitely in one direction. Two of these form an angle
  2. 4. An undefined term, this doesn’t have any dimensions and is the building block for everything else in geometry
  3. 6. An undefined term that has one dimension and extends infinitely in both directions.
  4. 8. An angle that has a measure of exactly 90°
  5. 11. A pair of non coplanar that do not intersect. They may or may not have the same slope.
  6. 14. A pair of lines that form right angles when they intersect.
  7. 17. A variation of the conditional statement, where the hypothesis and conclusion are switched. It can be represented as q→p
  8. 18. An angle that has a measure of 180°. Technically, it would also be a line.
  9. 19. A term that doesn’t have a clear definition in math. However, we know what these are based on our prior knowledge. Other terms are based on these
  10. 21. A variation of the conditional statement. The hypothesis and conclusion are negated. It can be represented as ¬p→¬q
  11. 23. A pair of adjacent or non adjacent angles whose measures add up to 90°
  12. 25. A type of triangle congruence theorem where if two sides and an included angle is congruent to another corresponding two sides and included angle of a second triangle, then the triangles are congruent.
  13. 26. A fact that can be easily proved after a theorem is proven
  14. 27. Lines that are in the same position and plane. They have an infinite amount of intersection points.
  15. 29. An angle that has a measure less than 90°
  16. 30. An undefined term that has two dimensions. It looks very similar to the walls and floors of our classroom and extends infinitely in all directions
  17. 31. An angle that has a measure of more than 90°, but less than 180°
  18. 33. A pair of coplanar lines that never intersect. They also have the same slope.
  19. 34. A pair of adjacent or non adjacent angles whose measures add up to 180°
  20. 36. A type of reasoning where you use patterns to determine what will happen.
  21. 37. A fact or statement that is simply accepted as true
Down
  1. 2. A type of angle pair formed by a transversal. The angles lie on alternate sides of the exterior of the transversal
  2. 3. A statement written in the form if-then, with a hypothesis and conclusion, like if hypothesis, then conclusion. It can also be represented as p→q, where p is the hypothesis and q is the conclusion.
  3. 5. A table used to determine whether a conditional statement is true or not.
  4. 7. A type of reasoning where you use facts and logic to determine what will happen
  5. 9. When two angles and an included side of a triangle are congruent to another corresponding two angles and an included side of a second triangle, this theorem is used to prove that the two triangles are congruent
  6. 10. A process that is used to make a geometric figure using only a compass and ruler/straightedge.
  7. 12. A pair of adjacent angles whose measures add up to 180°.
  8. 13. A fact about a term. Unlike others, they are directly related to the terms.
  9. 15. An abbreviation for the fact that corresponding parts of congruent triangles are congruent.
  10. 16. An invalid way of proving that two triangles are congruent. However, for right triangles, you can use another version of this for HL congruence
  11. 20. A line that intersects a pair of lines.
  12. 22. A type of angle pair formed by a transversal. The angles lie on alternate sides of the interior of the transversal
  13. 24. A type of angle pair formed by a transversal. They are in corresponding positions of the transversal
  14. 28. A fact that can be proved by using postulates, other theorems, definitions, and more!
  15. 29. When two angles and a non included side of a triangle are congruent to another corresponding two angles and a non included side of a second triangle, this theorem is used to prove that the two triangles are congruent.
  16. 32. A variation of the conditional statement, where the hypothesis and conclusion are switched and negated. It can be represented as ¬q→¬p
  17. 35. When two rays share a common endpoint, they form this term
  18. 38. A type of triangle congruence theorem that is used when all three sides of a triangle are congruent to 3 corresponding sides of a second triangle
