Across
  1. 3. the point on a line segment or coordinate plane that divides a segment into two congruent segments.
  2. 4. The sum of the areas of the faces of a geometric solid. How much it takes to cover it.
  3. 9. points where 3 or more polygons(faces) meet.
  4. 10. 3 or more points that are on the same line.
  5. 11. To cut an angle or line segment in half.
  6. 13. Two adjacent angles that create a line.
  7. 15. A closed figure whose sides are 3 or more line segments connected at their endpoints.
  8. 17. points, lines, segments, and rays that are on the same plane
  9. 18. a theorem that for all right triangles (leg₁)² + (leg₂)² = (hypotenuse)² (a²+b²=c²)
  10. 20. a transformation that flips a figure over a line.
  11. 21. The space a solid shape takes up, measured in cubic units. What it takes to fill it up.
  12. 22. Two angles whose sum = 90⁰
  13. 23. segments where the polygons(faces) meet.
Down
  1. 1. Two angles whose sum = 180⁰
  2. 2. the figure AFTER you move it in a transformation.
  3. 5. A polygon with each interior angle having a measure less than 180°- no dents.
  4. 6. having the same size or measurement:≅
  5. 7. angles that are formed by two intersecting lines but are NOT adjacent
  6. 8. polygons that make up the sides of the polyhedron.
  7. 12. a transformation that slides a figure on the coordinate plane.
  8. 14. A polygon in which at least one of the interior angles has a measure of more than 180 degrees. It has a dent (cave) in it.
  9. 15. The distance around the polygon. Add all the sides up.
  10. 16. a transformation that spins a figure around a fixed point
  11. 18. A solid (3-D figure) that is formed by polygons.
  12. 19. The figure BEFORE you move it in a transformation.
