Down
  1. 1. a triangle that is enclosed by and "fits snugly" inside another geometric shape or solid.
  2. 2. an eight-sided polygon or 8-gon
  3. 4. a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit.
  4. 5. a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
  5. 8. a seven-sided polygon or 7-gon.
  6. 9. a six-sided polygon or 6-gon.
  7. 10. a triangle in which all three sides are equal.
