Across
- 2. an angle that adds up to 180 degrees

- 6. two lines that intersect on the outside of a circle and the lengths are equal
- 9. the distance around a 2-dimensional object's exterior (outside)
- 10. the measure of any side or angle is equal to itself
- 11. two lines that intersect outside the circle and form an angle
- 15. the larger arc
- 18. (n)-the event in which both the first event and the second event occur
- 19. a line segment that goes from one corner to another, but is not an edge
- 20. a line segment that has both endpoints on a circle
- 22. if x=y and y=z, then x=z
- 23. (U) -the event in which the first event or the second event (or both) occur
- 24. in an isosceles triangle, the angles opposite the congruent sides are congruent
- 26. uses branches to find the probability of events occurring; can be used even if there are more than two probabilistic situations
- 28. speaking about an arc using degrees
- 29. the number of square units needed to fill up a region on a flat surface
- 31. the smaller arc
- 33. a proof that lists statements and reasons in a linear order, first to last, in columns
- 35. a figure can be rotated a certain degree about the center and will appear the same
- 36. a point on a line segment that divides it into two equal parts. The halfway point of a line segment
- 38. when the outcome of one event does not influence the outcome of the other
- 39. the sum of the three angles in any triangle is 180 degrees
- 40. an angle that adds up to 90 degrees
- 41. an angle in a circle with its vertex at the center of the circle
- 42. a rigid transformation that involves turning an entire figure about a fixed point
- 43. lie in the same plane and never intersect, same steepness/grow at the same rate, parallel lines have the same slope
- 44. a rigid transformation that involved sliding a figure to a new location
- 45. (Disjoint)- events that can never happen at the same time
Down
- 1. an angle in a circle with its vertex on the circle
- 3. means "at right angles" a line meeting another at a right angle
- 4. a figure can be folded on a line of symmetry where both halves of the figure will match or line up with each other exactly
- 7. if x=y, then y can be substituted in for x in any expression
- 8. lines that intersect at a right angle. Perpendicular lines have opposite reciprocal slopes
- 10. a rigid transformation that involves flipping a figure over the line of reflection
- 12. a midsegment between two sides of a triangle is half the length of and parallel to the third side of the triangle
- 13. when you are calculating a probability, but have been given additional information about an event that has already occured
- 14. a rectangle format that organizes data to examine the relationship between two categorical variables
- 16. set of points a fixed distance from a center and is defined by a central angle
- 17. all the outcomes in the sample space that are not in the original event
- 21. uses a rectangle format to find the probability of two situations occurring
- 25. how far it is from one point to another as you travel along an arc
- 27. means to divide into two equal parts
- 30. a line that divides a line segment into two equal parts, it also makes a right angle with the line segment
- 32. the study of geometry on a coordinate grid
- 34. when the three sides of a right triangle (a, b, and c) are positive integers
- 37. formed by two radii of a central angle and the arc between their endpoints on the circle
