Across
- 1. A three-dimentional closed room structure
- 2. The sum of the interior angles of this polygon is 180 degrees and sum of the exterior angles is 360 degrees
- 5. Two lines in the same plane that are at equal distance from each other and never meet
- 7. A closed two-dimensional figure in which the set of all the points in the plane are equidistant from a given point called “centre”
Down
- 1. A three-dimensional geometric figure that has a flat surface and a curved surface, pointed towards the top
- 3. Figures that are equiangular and equilateral
- 4. A two-dimentional polygon with 6 vertices , 6 edges and 6 angles
- 6. A three-dimentional figure whose area is 6a^2. It is the only regular hexahedron
