Across
- 5. A four-sided geometric figure with a pair of parallel sides.
- 6. The distance between the center of a circle and any point on its edge.
- 8. This is the total distance around the outside of a shape, obtained by calculating the sum of the lengths of all the sides.
- 11. It's a four-sided geometrical shape, where opposite sides are parallel and of equal length.
- 12. A straight line around which an object rotates.
- 13. This is a type of triangle where at least two sides are the same length.
Down
- 1. It's a tool used to measure and draw angles, usually in degrees.
- 2. This is an angle of less than 90 degrees.
- 3. It's a straight line starting from a fixed point and extending infinitely in one direction.
- 4. It's a 3D shape with two parallel circular bases connected by a curved surface.
- 6. It's a four-sided shape whose sides are all the same length and whose opposite angles are equal.
- 7. This is the vertical value of a pair of coordinates, indicating the position of a point along the y axis.
- 9. It's a 3D shape with a polygonal base and triangular faces that meet at a single point called the vertex.
- 10. It's a polygon with eight sides and eight angles.
