Across
- 5. Same shapes but not the same size
- 7. Is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints.
- 9. Is sometimes also called a gon or a grade
- 12. Means the same size and shape
- 13. Are lines that intersect at a right (90 degrees) angle.
- 14. Can be defined as a straight one- dimensional figure that has no thickness and extends endlessly in both directions.
Down
- 1. Is the unit of angle measure defined such that an entire rotation is.
- 2. Can be defined as the figure formed by two rays meeting at a common end point
- 3. Is the ratio of the circumference of a circle to its diameter.
- 4. Is a closed, two-dimensional shape with three straight sides
- 6. Is the angle made at the center of a circle by an arc whose length is equal to the radius of the circle.
- 8. Is a particular dihedral angle; it is the angle between two intersecting arcs of great circles on a sphere.
- 10. Is part of a line that has a fixed starting point but does not have an endpoint.
- 11. Usually refers to a portion of a circle
- 13. can be defined as two lines in the same plane that are at equal distance from each other and never meet.
