# GEOMETRY

##### Across
1. 3. "the Father of Geometry"
2. 6. the point that cuts a segment in half
3. 7. the study of points, lines, planes, and shapes
4. 11. the point where 2 rays meet to make an angle
5. 12. 2 angles with a sum of 90
6. 14. 2 adjacent angles that are supplementary
7. 15. statements accepted as true without proof
8. 17. has one endpoint and goes forever
9. 18. angles are measured by these
10. 19. this is formed by 2 opposite rays
11. 20. any angle less than 90 degrees
##### Down
1. 1. it has 2 endpoints and can be measured
2. 2. a 90 degree angle
3. 4. describes a location and has no width or depth
4. 5. segments with the same measure are called this
5. 8. represented by a flat surface that extends in all directions
6. 9. a ray or line that cuts an angle into 2 equal angles
7. 10. 2 angles with a sum of 180
8. 11. angles formed by intersecting lines and are always equal
9. 12. points on the same line
10. 13. points in the same plane
