Across
- 5. 2 angles directly across from each other on intersecting lines. They are always congruent.
- 8. Opposite sides are parallel and congruent. Consecutive angles a supplementary and diagonals bisect each other.(hint:it is a shape)
- 12. 2 angles with measures that sum to 180 degrees. They do not have to be adjacent.
- 14. The common endpoint of an angle. Where the sides intersect.
- 18. Points that do not lie on the same line. The opposite of collinear.
- 19. 2 angles with measures that sum to 90 degrees. They do not have to be adjacent.
- 20. A line that ends in one direction. And is infinite in the other direction.
Down
- 1. As only one pair of opposite sides that are parallel. Consecutive angles are supplementary.(hint:is is a shape)
- 2. As four right angles. Its diagonals are congruent.(hint:it is a shape)
- 3. Points that lie on the same line. The opposite of non-collinear.
- 4. Exactly two pairs of consecutive congruent sides. One pair of opposite angles are congruent and diagonals are perpendicular.(hint:it is a shape)
- 6. As four consecutive sides. Diagonals are perpendicular and bisect opposite angles.(hint:it is a shape)
- 7. A diagram showing a relationship between two or more points.Contains an X and Y axis.
- 9. Adjacent angles that are supplementary.Combined they form a straight line.
- 10. The intersection of 2 rays at an endpoint. How we measure how close to a circle something is.
- 11. Lines that intersect at a 90 degree angle. In other words it creates a right angle.
- 13. Is made up of points with no thickness or width. It never ends.
- 15. Adjacent angles that are supplementary. Combined they form a straight line.
- 16. Points that lie on the same plane. The opposite of non-coplaner.
- 17. Points that do not lie on the same plane. The opposite of collplanar.
