Across
- 1. a flat or plane, two-dimensional closed shape bounded with straight sides
- 3. a three-dimensional geometric shape with a polygon as its base and the lateral surfaces as triangles that meet at a common vertex
- 5. two numbers or sometimes a letter and a number, that locate a specific point on a grid
- 9. a four sided-polygon with two parallel sides longer than the others
- 12. a triangle in which two sides are of equal length
Down
- 1. a three-dimensional solid object in which the two ends are identical
- 2. the amount of space covering the outside of a three-dimensional shape
- 3. two straight lines that meet or intersect at 90°
- 4. the amount of space occupied by a 2-D figure
- 6. a pattern that can be cut and folded to make a model of a solid shape
- 7. a triangle having three unequal sides, as a triangle that is neither equilateral nor isosceles
- 8. the space inside a three-dimensional object, like a box
- 10. measures the total length around the outside of a shape
- 11. the point where two lines meet to form an angle
