Across
  1. 2. -A triangle that contains only angles that are less than 90 degrees.
  2. 9. -If B is between A and C, then AB + BC = AC
  3. 11. -lines in the same plane that never intersect
  4. 15. -a pair of adjacent angles whose noncommon sides are opposite rays.
  5. 17. -points that lie on the same line
  6. 19. -A pair of opposite congruent angles formed by intersecting lines
  7. 20. -If a hypotenuse and leg of one right triangle are congruent to the corresponding hypotenuse and leg of a second right triangle, then the triangles are congruent.
Down
  1. 1. -Angles formed by a transversal cutting through 2 or more lines that are in the same relative position.
  2. 3. -a ray that divides an angle into two congruent angles
  3. 4. -two angles whose sum is 180 degrees
  4. 5. -A point that divides a segment into two congruent segments
  5. 6. -lines that intersect to form right angles
  6. 7. -two angles whose measures add to 90 degreees
  7. 8. -If P is in the interior of <RST, then m<RSP + m<PST = m<RST
  8. 10. -a line that intersects two or more coplanar lines at different points
  9. 12. -A triangle with one angle that is greater than 90 degrees.
  10. 13. -points that lie on the same plane
  11. 14. -a segment, ray, line, or plane that intersects a segment at its midpoint
  12. 16. -Two angles that share a common side and have the same vertex
  13. 18. -a part of a line with two endpoints
