Geometry
Across
- 4. the measure of a regions size on a surface
- 6. the branch of mathematics concerned with specific functions of angles and their application to calculations
- 8. the branch of mathematics concerned with the properties and relations of points, lines,surfaces, solids,and higher dimensional analog
- 9. the distance across a circle through the centre
- 12. a point that is in the middle of the line joining two points
- 14. a figure plane with four straight sides and four straight angles
- 16. a half infinite line(also known as a half line) with one of the two points and taken to be at infinity
- 18. a statement that can be demonstrated to be true by accepted mathematical operations and arguments
- 20. the distance that surrounds a circle
Down
- 1. the space occupied within the boundaries of an object in three-dimensional space
- 2. a two dimensional shape with 4 sides, four vertices,and four angles
- 3. a dot in a plane or a piece of paper
- 5. a point where two or more curves, lines, or edges meet.
- 7. the distance from the center of the circle to any point on its circumference
- 10. three sided polygon
- 11. a round plane figure whose boundary consists of points equidistant from a fixed point (the center)
- 13. a polygon composed of four triangular faces, six straight edges, and four vertex corners.
- 15. each pairs of opposite angles made by two intersecting lines
- 17. a two dimensional doubly ruled surface spanned by two linearly independent vectors
- 19. when both the hypotenuse and conclusion are negated
