Across
- 2. 2 angles that have equal measurement, congruent
- 5. points that are on the same line
- 7. if a,b,c are on the same line and b is between c and a then ab + bc= ac
- 9. the angles that are across from each other and equal the same degrees
- 11. 2 angles that add up to 180
- 12. a line= 180 degrees
- 16. a flat surface made up of points and extends forever in all directions
- 18. the formula used to find the coordinates of the midpoint between 2 endpoints
- 19. 2 angles that share a common vertex and side
- 21. where the 2 ray sides intersect (the endpoint)
- 22. a line that extends forever in only one direction
- 23. lines that never touch or intersect
- 24. a segment, line, or plane that goes through a line at its midpoint
- 25. points that are on the same plane
- 26. the formula used to find the distance between 2 points on a coordinate plane
- 28. If 2 segments have the same length then they are congruent
- 29. points that are not on the same line
Down
- 1. if Labd and Ldbc are adjacent then abd+dbc=abc
- 3. a measurable part of a line consisting of 2 endpoints
- 4. 90 degree angle
- 6. more than 90 degrees
- 8. a line, segment, or ray perpendicular to the segment at its midpoint
- 10. a line or ray that equally divides an angle into 2 parts
- 13. 2 lines that intersect to make a 90-degree angle (right)
- 14. adjacent angles that are supplementary. when combined they form a straight line
- 15. a location with no size or shape
- 17. the intersection of 2 rays at an endpoint
- 19. an angle that measures less than 90 degrees
- 20. 2 angles that add up to 90
- 27. made up points with no area just length and extends forever in both direction
