Across
  1. 3. the point (corner) where three or more edges of a figure meet
  2. 6. angle, an angle that measures greater than 90° but less than 180°
  3. 11. all side lengths of a polygon are congruent in measure
  4. 13. of equal measure, having exactly the same size and same shape
  5. 15. Figure, a polygon with sides and/or angles that are not all congruent
  6. 17. Dimensional figure, a figure that has measurements including length, width (depth), and height
  7. 20. two rays with a common endpoint (the vertex)
Down
  1. 1. angle, an angle that measures less than 90°
  2. 2. a closed figure with at least 3 sides, where all sides are straight (no curves)
  3. 4. Dimensional figure, a figure with two basic units of measure, usually length and width
  4. 5. applying an attribute to categorize a sorted group
  5. 7. a line segment that forms the boundary of a two-dimensional figure
  6. 8. a change from one measurement unit to another measurement unit without changing the amount
  7. 9. a linear measurement of the distance around the outer edge of a figure (L + W + L + W)
  8. 10. a flat surface of a three-dimensional figure
  9. 12. length x width
  10. 14. figure, a polygon with all sides and angles congruent
  11. 16. where the sides of two faces meet on a three-dimensional figure
  12. 18. angle, an angle (formed by perpendicular lines) that measures exactly 90°
  13. 19. the measurement attribute of the amount of space occupied by matter ( L x W x H)
