Across
- 2. Add up to 90 degrees. Form a right angle.
- 5. Shapes that are the same in shape, but not size.
- 6. Split into two. Cuts an angle or line into equal parts.
- 11. The extent of a shape on the coordinate plane. Measured in square units.
- 13. a²+b²=c². Can only be used in right triangles.
- 16. Ball-shaped 3-D figure. Contains a circle in its center.
- 17. Formed by intersecting lines. Measured in degrees.
- 19. Straight. Continues on forever in both directions.
Down
- 1. 3-dimensional figure. Has two identical shapes as its bases.
- 3. Never intersecting. Will never come together under any circumstances.
- 4. The perimeter of a circle. 2πr.
- 7. Add up to 180 degrees. Form a straight angle.
- 8. The location of a point. (x,y)
- 9. A change in a geometric shape. Includes rotation, translation, reflection, and dilation.
- 10. The amount of space an object takes up. Measured in cubic units.
- 12. Shapes that are the same in shape and size. All angles and sides are the same.
- 13. Plane figure. Has at least 3 sides and angles.
- 14. How far it is between two points. Determined using the coordinates of two points.
- 15. The subject of this class. Includes the study of angles, flat shapes, and 3-dimensional shapes
- 18. A number found between 3 and 4. Often expressed with the symbol π.
