Geometry
Across
- 4. a flat surface of a 3D object
- 6. a solid object with 2 congruent and parallel bases
- 8. the surface included inside set lines
- 9. figures that have the same shape but are not necessarily the same size
- 11. an irrational number that is found by dividing a circle's circumference by its diameter
- 12. a closed solid that has 2 parallel usually curved bases connected by a curved surface
- 14. the ratio of 2 corresponding lengths in similar geometric shapes
- 15. area the sum of all of the areas of a 3D object's faces
- 16. a solid object with a polygon base and a vertex (point) at the the opposite end with triangular sides
- 18. a technique used to measure the height of an inaccessible object such as buildings or trees
- 19. the border or outer boundary of a 2 dimensional figure
- 20. a pattern made when the flat surfaces of a 3D object is laid our showing each face
Down
- 1. the distance from the center to any point on the edge of a circle
- 2. the same shape and the same size
- 3. one of two parallel congruent sides of a 3D object
- 5. the distance through the center of the circle
- 7. the amount of space a 3D object fills
- 10. used to measure distances or lengths that are difficult to measure directly
- 11. a 3D shape that has flat surfaces and straight edges
- 13. the distance around a circle
- 17. the intersection of 2 faces this is a line
