Across
  1. 3. Points that lie on the same plane. They are not necessarily congruent, just on the same plane.
  2. 4. 2 segments that have the exact same measure. They also have the same length.
  3. 5. 2 angles directly across from each other. They are always on intersecting lines.
  4. 7. It is 2 angles. They add up to 180 degrees.
  5. 10. Consists of 2 angles. They add up to 90 degrees.
  6. 11. Points that lie on the same line. It has to be 3 or more points to be considered one.
  7. 14. Also consists of 2 angles. They have the same measure.
  8. 15. It is a location. It has no size or shape.
  9. 18. Most commonly 2 lines. They will never intersect.
  10. 19. It is a measurable part of a line. It consists of 2 endpoints.
  11. 20. The study of triangular measurements. SOH CAH TOA is used in it.
Down
  1. 1. Opposite sides are congruent. Opposite angles are congruent. Consecutive angels are supplementary. Diagonals bisect each other.
  2. 2. 2 angles that share a common side. They also share a common vertex.
  3. 6. It is made up of 2 points. Any 2 points form a line.
  4. 8. Used to find the missing side of a right angle. The formula is a2+b2=c2.
  5. 9. Line or ray that divides an angle. It divides the angle into 2 equal parts.
  6. 12. A closed figure. It is formed by 3 or more line segments, called sides.
  7. 13. This term extends indefinitely in one direction. It also has a fixed starting segment.
  8. 16. This term is a flat surface made up of points. Any 3 points make up a plane.
  9. 17. Adjacent angles that are supplementary. Combined, they form a straight line.
