Across
  1. 3. triangle with a right angle.
  2. 6. parallelogram with consecutive sides congruent.
  3. 7. segments that have the same length.
  4. 8. are noncoplanar lines they will not intersect.
  5. 11. two coplanar angles with a common vertex and a common side between them
  6. 12. points that lie on the same plane.
  7. 14. has no size; length, width, or height. It is represented by a dot and named by a capital letter.
  8. 17. in a right triangle, the sum of the squares of the legs is equal to the square of the hypotenuse
  9. 21. union of 3 or more coplanar segments that meet only at endpoints such that at most two segments meet at one endpoint and each segment meets exactly two other segments.
  10. 22. line, ray segment, or plane that divides a segment into two congruent segments.
  11. 25. set of points which has infinite length but no width or height. A line is named by a lower case letter or by any two points on the line.
  12. 26. quadrilateral with both pairs of opposite sides parallel.Rectangle – parallelogram with a right angle.
  13. 28. triangle with at least two sides congruent.
  14. 29. the figure formed by three segments joining three noncollinear points. Each of the three points is a vertex of the triangle and the segments are the sides.
  15. 31. comparison of two numbers by division.
  16. 33. triangle with an obtuse angle
  17. 34. triangle that has all acute angles.
  18. 35. segment from the vertex of a triangle to the midpoint of the opposite side.
  19. 37. angles that have the same measure.
  20. 38. all sides congruent and all four right angles.
  21. 40. points that lie on the same line.
  22. 46. two lines that intersect to form right angles.
  23. 47. angle whose measure is 180 degrees.
Down
  1. 1. angle whose measure is 90 degrees.
  2. 2. ray that divides an angle into two congruent adjacent angles.
  3. 4. equation that states two ratios are equal.
  4. 5. angle whose measure is greater than 90 degrees but less than 180 degrees.
  5. 9. segment from the vertex of a triangle perpendicular to the line containing the opposite side.
  6. 10. the non-adjacent angles formed by two intersecting lines.
  7. 13. angle whose measure is between 0 degrees and 90 degrees.
  8. 15. two triangles are congruent if corresponding sides are congruent and corresponding angles are congruent.
  9. 16. segment that connects two points on the circle.
  10. 18. branch of mathematics that deals with points, lines, planes and solids and examines their properties.
  11. 19. part of a line that consists of two points called endpoints and all points between them.
  12. 20. the set of points in a plane that are equidistant from a fixed point called the center.
  13. 21. two lines are parallel if they are coplanar and do not intersect.
  14. 23. triangle with all sides congruent.
  15. 24. points that do not lie on the same line.
  16. 27. segment whose endpoints are the center of the circle and a point on the circle.
  17. 30. quadrilateral with exactly one pair of opposite sides parallel.
  18. 32. is the part of a line that contains an endpoint and all points extending in the other direction.
