Across
- 6. a quadrilateral with both pairs of opposite sides parallel and all sides the same length
- 8. is a geometrical shape, which has five sides and five angles.
- 9. a quadrilateral has two pairs of opposite sides equal in length and interior angles are at the right angles
- 11. a quadrilateral with two pairs of parallel sides and opposite angles are equal in measure.
- 13. is a quadrilateral where all the four sides and angles are equal and the angles at all the vertices are equal to 90° each.
- 14. is a round shape in a 3d plane, whose radius is extended to three dimensions (x-axis, y-axis and z-axis).
Down
- 1. a polygon, which is made of three sides and consists of three edges and three vertices. Also, the sum of its internal angles equals to 180o
- 2. is also three dimensional solid having 6 faces, 8 vertices and 12 edges but the faces of the cuboid are in a rectangular shape.
- 3. is a Locus of all points at a fixed distance from a reference central point
- 4. is a three-dimensional shape which has 6 faces, 8 vertices and 12 edges. The faces of the cube are square.
- 5. is a solid which has a circular base and narrows smoothly from the surface to the top at a point called apex or vertex.
- 7. is a quadrilateral with one pair of parallel opposite sides.
- 8. These are made up of line segments and no curves. They are enclosed structures based on different lengths of sides and different angles
- 10. is a 3d solid shape that has two parallel circular bases connected by a curved surface. It has no vertex.
- 12. is a quadrilateral, a closed flat geometric shape in which two sets of neighboring or adjacent sides are congruent (equal in length). Its diagonals meet at right angles.
