Across
- 3. a 3D shape that is formed with a square base and 4 triangles building up
- 6. the space around a 2D shape
- 9. the area of the faces/sides (2D side shape of a 3D shape) of a 3D shape
- 12. a triangle with two sides that are the same length
- 14. a number showing a spot on a coordinate plain, either in distance or height x or y from 0
Down
- 1. a angle that measures 90 degrees,one straight line vertical and one straight line horizontal connected at a vertex would make a right angle
- 2. lines that intersect each other at right angles
- 4. the point where two lines of a polygon meet to form an angle
- 5. the total amount of space inside a 3D shape, how many unit cubes fit inside
- 7. a triangle that has all unequal sides and angles
- 8. a polygon (shape) that has equal angles and sides, a square
- 10. the space inside a 2D shape, how many unit squares fit inside
- 11. Lines segments that connect with each other at vertices to form a 2D shape
- 13. an unfolded 3D shape that is flat and 2D, showing each side of a 2D shape
