Geometry Puzzle

1. Angles that are formed when two lines pass through each other. Angles are supplementary and share a base.
4. The act of existing in the same coordinate plane. Can be be vastly spaced apart.
7. A section/part of a straight line. Found in between two points labeled the end points.
8. The number of possible arrangements. Found using the number of objects and objects requested.
10. Events that require each other to occur. The outcomes of each event have an effect on the other(s).
12. A figure created by two lines. Found in most shapes.
13. Two angles created by a division of a straight line. Both angles add up to 180 degrees.
14. A statement that has, or can be, proven to be correct and true. Usually accepted as true through common knowledge.
16. A set of points existing on a line. The Line used by the points is also straight.
17. The result of a probable event. The aftereffect of an experiment.
18. An angle that measures more than 90 degrees. Also measures less than 180 degrees.
19. The accuracy and truthfulness of a statement. Corresponds to the word Valid and is used to describe bi-conditional statements.
20. The point found evenly between two other points on a line. Line is found on a coordinate plane.

2. An angle that measures less than 90 degrees. Appearance is similar to the less-than sign.
3. Two or more lines that do not touch or intersect. The lines are also spaced away from each other evenly.
5. An angle that measures 90 degrees exactly. Can be identified by a symbol similar in appearance to a box.
6. An example that proves a bi-conditional statement to be wrong. Can also apply to any statement or rule.
9. Angles that share a side but do not cross over. Neighboring angles that share a vertex.
11. Every possible result or outcome from an experiment. May be represented by a tree diagram.
15. The chance of something occurring, such as an event. Represented by a percentage or fraction.
