  1. 2. a triangle whose two sides are equal in length.
  2. 4. a theorem with a short proof connecting it to an already established theorem.
  3. 10. Every point of a transformed figure "slides" in the same direction and distance.
  4. 12. exterior- angles created when a transversal connects two lines, and they are outside of the other two lines and on the opposing sides of the transversal.
  5. 15. a transformation that alters the object's size. The objects can be enlarged or shrunk via dilation.
  6. 16. polygons with congruent angles.
  7. 18. pair- Angles creating a straight line that are adjacent and supplementary.
  8. 19. One of the fundamental, undefinable notions in geometry is the idea that it is flat and extends indefinitely in all directions.
  9. 20. Straight lines that are parallel and do not intersect at any point.
  10. 21. starts from one location and proceeds continuously in one direction.
  11. 22. Comparison of two quantities by division.
  12. 25. is a point that lies at the end of a ray or line segment.
  13. 28. A reflection is an isometric mapping from a metric space to itself using a set of fixed points called a hyperplane.
  14. 29. a planar shape made up of a closed polygonal chain linked by a finite number of straight line segments.
Down
  1. 1. is when anything is split into two equal or similar portions, typically by a line.
  2. 3. line segment between two points on a line.
  3. 5. factor- any two equivalent lengths of the sides of two similar figures divided by one another.
  4. 6. a set of points that has no thickness but its length goes on forever in two opposite directions.
  5. 7. Crossing of two or more lines.
  6. 8. share a vertex and a side but not any interior points.
  7. 9. line- a planar geometry proof requiring an additional line.
  8. 11. similar-looking but not necessarily identical-sized figures.
  9. 13. The mapping of all the points of a figure according to a common operation.
  10. 14. angles- Two nonadjacent angles formed by intersecting lines or segments.
  11. 17. angle- Angles with identical relative positions.
  12. 23. a formula for determining the equality of two ratios.
  13. 24. identically sized and shaped objects.
  14. 26. side interior- angles created when a transversal intersects two lines, and they are situated between the other two lines on the same side of the transversal.
  15. 27. lines that are not parallel to one another.
