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