Across
- 6. the parallel sides of a trapezoid
- 7. is a quadrilateral with exactly two pairs of consecutive congruent sides, unlike a parallelogram The opposite sides of a kite are not congruent or parallel.
- 9. if one pair of opposite sides of a a quadrilateral is both congruent and parallel, then the quadrilateral is a parallelogram.
- 10. if a quadrilateral is a parallelogram, then it’s consecutive angles are supplementary.
- 14. the non parallel side of a trapezoid
- 16. when the legs of the trapezoid are congruent.
- 18. is a quadrilateral with both pairs of opposite sides parallel.
- 23. is a parallelogram with all four sides congruent,A rhombus has all the properties of a parallelogram.
- 24. if a quadrilateral is both a rectangle and a rhombus, then it is a square.
- 31. if a quadrilateral is a parallelogram, then its opposites sides are congruent.
- 35. if a trapezoid is isosceles, then each pair of base angles is congruent.
- 36. are formed by the base and one of the legs of a trapezoid.
Down
- 1. if the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.
- 2. of the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle.
- 3. if one pair of consecutive sides of a parallelogram are congruent, the parallelogram is a rhombus.
- 4. the mid segment of a trapezoid is parallel to each base and its measure is one half the sum of the lengths of the bases.
- 5. a segment that connects any two nonconsecutive vertices.
- 8. if a quadrilateral is a parallelogram, then each diagonal separates the parallelogram into two congruent triangles.
- 10. if both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram.
- 11. a trapezoid is isosceles if and only if it’s diagonals are congruent.
- 12. if a parallelogram is a rhombus, then its diagonals are perpendicular.
- 13. if a quadrilateral is a kite, then it’s diagonals are perpendicular.
- 15. if one diagonal of a parallelogram bisects a pair of opposite angles, then the parallelogram is a rhombus.
- 17. is a quadrilateral with exactly one pair of parallel sides.
- 19. if a parallelogram is a rhombus, then each diagonal bisects a pair of opposite angles.
- 20. if the diagonals of a parallelogram are perpendicular, then the parallelogram is a rhombus.
- 21. if a trapezoid has one pair of congruent base angles, then it is an isosceles trapezoid.
- 22. if a parallelogram has one right angle then it has for right angles.
- 25. if a quadrilateral is a parallelogram, then it’s opposite angles are congruent.
- 26. is a parallelogram with for right angles by definitions, a rectangle has the following properties: all four are right angles, opposite sides are parallel and congruent, opposite angles are congruent, consecutive angles are supplementary, diagonals bisect each other.
- 27. the sum of the interior angle measures of an n-sided convex polygon is (n-2)*180.
- 28. if a quadrilateral is a parallelogram, then it’s diagonals bisect each other.
- 29. if both pairs of opposite angles of a quadrilateral are congruent, then the quadrilateral is a parallelogram.
- 30. is a parallelogram with four congruent sides and four right angles.
- 31. the sum of the exterior angle measures of a convex polygon, one angle at each vertex is 360.
- 32. if a parallelogram is a rectangle, then it’s diagonals are congruent.
- 33. is the segment that connects the midpoints of the legs of the trapezoid.
- 34. if a quadrilateral is a kite, then exactly one pair of opposite angles is congruent.
