Across
  1. 2. A line, segment or ray that hits at a vertex and cuts the angle into congruent angles
  2. 4. Two lines that intersect to form right angles, where the slopes are negative reciprocals and form adjacent congruent angles
  3. 7. An infinitely thin and infinitely long collection of points extending in two opposite directions
  4. 9. A line, segment, or ray that intersects a segment at its midpoint and forms 2 congruent parts
  5. 11. If B is between A and C, then AB+BC=AC
  6. 12. A geometric figure made up of 2 rays that have a common endpoint called the vertex
  7. 14. Two angles whose measurements add up to 90°
  8. 15. Two endpoints and all points of the line between the two endpoints, where the point in the middle of the line segment is called the midpoint
Down
  1. 1. Two adjacent angles whose noncommon opposite sides form opposite rays
  2. 3. Two angles whose measurements add up to 180°
  3. 5. 2 non-overlapping angles that share a common side and a common vertex
  4. 6. If D is in the interior of ABC then m<ABD + m<CBD = m<ABC
  5. 8. Two angles sharing a common vertex whose noncommon sides form opposite rays.
  6. 10. Lines that never intersect, go in the same direction, are the same distance apart, and have the same slope
  7. 13. Part of a line that has one endpoint and goes on infinitely in only 1 direction
