Across
  1. 2. A transformation that turns a figure around a fixed point without flipping it; like turning a Star Wars star-map symbol
  2. 8. A reasoned prediction based on observed patterns; like a prediction about a repeating Arabic geometric tile design
  3. 11. Describes lines that intersect to form right angles; like two paths in an Inca terrace diagram
  4. 14. A transformation that flips a figure across a line to create a mirror image; like a Basque textile pattern
  5. 16. A quadrilateral with four right angles; like the outline of a Basque pelota court
  6. 17. A line that intersects a circle at exactly two points; like a flight path across a Death Star diagram
  7. 19. TRIANGLE A triangle with at least two congruent sides; like a Mayan pennant shape (2 words)
  8. 20. A segment with both endpoints on a circle; like a connection between two points on a Mayan calendar circle
  9. 22. Features used to describe a figure, such as its sides, angles, and lines of symmetry; like details on an Egyptian shape label
Down
  1. 1. A segment that passes through a circle’s center and has endpoints on the circle; like a line across an Aztec calendar stone
  2. 3. A figure formed by two rays with a common endpoint; like the opening between two rays on a Basque festival flag
  3. 4. ANGLE An angle whose vertex is the center of a circle; like an angle made by two radii in an Egyptian sun-disk design (2 words)
  4. 5. Describes a polygon whose vertices all lie on a circle; like a hexagon placed inside an Indian rangoli circle
  5. 6. A polygon with three sides and three vertices; like a triangular face on an Aztec temple model
  6. 7. A quadrilateral with four congruent sides and four right angles; like an Inca stone-block design
  7. 9. A part of a line with two endpoints; like a straight connection between two points on an Inca road map
  8. 10. HEXAGON A six-sided polygon with all sides and all angles congruent; like a shape in an Indian mandala (2 words)
  9. 12. A line, ray, or segment that divides an angle or segment into two congruent parts; like a divider in a Mayan temple plan
  10. 13. The set of all points in a plane that are the same distance from a center point; like the outline of the Death Star
  11. 15. A quadrilateral with four congruent sides; like a four-sided Arabic tile that does not need right angles
  12. 17. The property of matching parts in a figure or design; like the balanced halves of an Indian rangoli pattern
  13. 18. A curved portion of a circle; like part of the edge of an Aztec circular calendar design
  14. 21. A segment from the center of a circle to a point on the circle; like a line from the center of an Egyptian sun disk to its edge
