Across
  1. 2. - A closed, two-dimensional figure made up of straight line segments connected end to end.
  2. 4. - Two angles whose measures add up to 90°.
  3. 5. - A three-dimensional shape with two parallel, congruent circular bases connected by a curved surface.
  4. 9. - Two lines, segments, or rays that intersect to form a right angle (90°).
  5. 12. - The amount of space a three-dimensional figure occupies.
  6. 13. - A line segment where two faces of a polyhedron meet.
  7. 14. - The resulting figure after a transformation has been applied to the preimage.
  8. 18. -Two angles whose measures add up to 180°.
  9. 20. - Two angles that share a common side and a common vertex, but do not overlap.
  10. 24. - A transformation that turns a figure around a fixed point, called the center of rotation.
  11. 25. - A pair of adjacent angles whose non-common sides form a straight line, adding up to 180°.
  12. 27. - A ray that divides an angle into two equal (congruent) angles.
  13. 28. - The total area of all faces and curved surfaces of a three-dimensional shape.
  14. 30. - The amount of space inside a two-dimensional shape or figure.
  15. 31. - A point where three or more edges of a polyhedron meet.
  16. 32. - The two rays that form an angle, or the line segments that form the boundary of a polygon.
Down
  1. 1. - Angles that have the same measure.
  2. 3. - A three-dimensional figure made up of flat polygonal faces, straight edges, and vertices.
  3. 5. - The perimeter or distance around a circle.
  4. 6. - The total distance around the boundary of a polygon.
  5. 7. - A three-dimensional shape with a circular base and a single vertex, connected by a curved surface.
  6. 8. - A flat surface on a polyhedron.
  7. 10. - A two-dimensional pattern that can be folded to form a three-dimensional figure
  8. 11. - A pair of opposite angles formed when two lines intersect; they are always congruent.
  9. 15. - A face of a three-dimensional figure, often used as a reference for measurements.
  10. 16. - A transformation that slides a figure a certain distance in a given direction.
  11. 17. - A transformation that "flips" a figure over a line, creating a mirror image.
  12. 19. - A part of a line that starts at a point (called the endpoint) and extends infinitely in one direction.
  13. 21. - A change in the position, shape, or size of a figure; types include translation, reflection, rotation, and dilation.
  14. 22. - A polyhedron with two parallel, congruent bases connected by rectangular faces.
  15. 23. -The common endpoint where two sides or rays meet in an angle, polygon, or polyhedron.
  16. 26. - The original figure or shape before a transformation.
  17. 29. - Formed by two rays (sides) with a common endpoint (vertex), representing the amount of rotation needed to bring one ray onto the other.
