Across
- 4. Points that lie on the same plane. Opposite of non-coplanar.
- 7. Non-coplaner lines that never intersect. Usually on a 3-D object.
- 10. Made up of points. Two points make up this thing.
- 13. Has the same shape and size. Angles and sides are congruent.
- 15. A line having two endpoints. These points have the shortest distance between them.
- 18. Two segments that have the same length. For example segment AD and AB are equal because they both have a length of 10.
- 19. Angle that measures less than 90 degree. An angle that is Smaller than a right angle.
- 20. A Flat surface. Made up of points and extends indefinitely in all directions.
Down
- 1. two coplaner lines that never intersect. For example AB//CD.
- 2. Formula used to find distance. d=the square root of (x1-x2)+(y1+y2) squared.
- 3. Formula used to find the midpoint. m=(x1-x2/m,y1-y2/m)
- 5. A location that has no size. A location that has no shape.
- 6. It is a straight line. Passes through one point
- 8. In a right triangle. Where the right angle points.
- 9. Measures exactly 90 degrees.An example is a corner of a square.
- 11. triangles where all the sides were equal. All angles are 60 degrees.
- 12. Points that lie of the same line. Opposite of non-collinnear.
- 14. Angle that is greater than 90 degrees. An angle that is less than 180 degree.
- 16. The common endpoint of an angle.For example, the corner of a triangle.
- 17. the intersection of two rays at an endpoint. Their are three of these in a triangle.
