- 2. an object, shape, or arrangement in the form of a pyramid.
- 4. a plane figure with four equal straight sides and four right angles.
- 5. a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
- 6. a solid geometric figure with straight parallel sides and a circular or oval cross section.
- 9. a plane figure with at least three straight sides and angles, and typically five or more.
- 11. a plane figure with five straight sides and five angles.
- 14. a plane figure with three straight sides and three angles.
- 16. a four-sided plane rectilinear figure with opposite sides parallel.
- 17. a quadrilateral with only one pair of parallel sides.
- 19. a triangle in which one of the angles is an obtuse angle.
- 20. a plane figure with ten straight sides and angles.
Down
- 1. a round solid figure, or its surface, with every point on its surface equidistant from its center.
- 3. a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
- 7. a plane figure with nine straight sides and nine angles.
- 8. a triangle with a right angle.
- 10. a plane figure with eight straight sides and eight angles.
- 12. a triangle with three acute angles, that means they measure less than 90°.
- 13. a plane figure with six straight sides and angles.
- 15. neither parallel nor at right angles to a specified or implied line; askew; crooked.
- 18. side by side and having the same distance continuously between them.
