##### Across
1. 1. is a four sided shape that has two sides that are parallel and two sides that are not parallel
2. 4. is a four sided shape that is made up of two pairs of parallel lines and that has four right angles; a shape in which one pair is longer than the other pair
3. 5. is a line segment joining two nonconsecutive vertices of a polygon or polyhedron. Informally, any sloping line is called diagonal.
4. 8. is a polygon with four edges (or sides) and four vertices or corners.
5. 9. are points where sides meet
6. 10. are Angles whose measures add up to 90 degrees
7. 11. are lines that intersect at right angles to each other
8. 13. is a flat shape with 4 equal straight sides. It looks like a diamond. . All sides have equal length.
9. 15. are two sides that appears one right after another and that share an endpoint.
10. 18. are sides that are not adjacent.
11. 19. are angles that occur one right after the other. Consecutive angles are on either end of the same line segment in a polygon.
12. 23. are corresponding parts refer to the exact same shape
13. 24. is a regular quadrilateral that has four equal sides and four equal angles
##### Down
1. 2. is a four sided shape made up of two pairs of straight parallel lines that are equal in length
2. 3. is a line that cuts in half
3. 6. are lines that never meet
4. 7. are two Angles when they add up to 180 degrees
5. 12. is a shape that has two sides of equal length and sometimes having at least two sides of equal length
6. 14. is a segment that connects the midpoints of two sides of a triangle.
7. 16. are points that lie on the same plane
8. 17. Pairs are Adjacent supplementary angles
9. 20. are Equal sides
10. 21. are equal angles
11. 22. is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.
