Shapes in Geometry

4. a four-sided, or quadrilateral, geometric figure in which all four sides are of the same length and each of the two pairs of opposite sides are parallel to each other
6. a three-dimensional shape, with a polygonal base and flat triangular faces, which join at a common point called the apex
7. a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges
8. a closed flat shape, having four sides, and each angle equal to 90 degrees
10. a polygon with 6 sides and 6 angles
11. a three-dimensional shape in geometry that narrows smoothly from a flat base to a point called the apex or vertex

1. a three-dimensional object that is round in shape, no faces, no vertices, no edges
2. a round-shaped figure that has no corners or edges
3. a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance
5. a plane figure with four equal straight sides and four right angles
6. a polygon with 5 sides and 5 angles
9. a polygon with three corners and three sides
