Across
- 3. a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
- 4. straight line from the center to the circumference of a circle or sphere
- 7. line In geometry, a horizontal line is one which runs from left to right across the page. It comes from the word 'horizon', in the sense that horizontal lines are parallel to the horizon. The horizon is horizontal. Its cousin is the vertical line which runs up and down the page.
- 8. measurable extent of some kind, such as length, breadth, depth, or height.
- 10. prepare a preliminary version of (a text).
- 11. lines In geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. By extension, a line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are said to be parallel
- 12. projection a drawing or map made using orthographic projection.
- 14. line Object lines are solid heavy lines, .7 mm to .9 mm. These lines define the shape of the object portrayed and are the outermost outline of the object. A round bar is shown as a circle in one view and a rectangle in the other. Both would be drawn with object lines.
Down
- 1. lines Perpendicular lines are lines that intersect at right angles. If you multiply the slopes of two perpendicular lines in the plane, you get . That is, the slopes of perpendicular lines are opposite reciprocals .
- 2. lines A vertical line is one the goes straight up and down, parallel to the y-axis of the coordinate plane. All points on the line will have the same x-coordinate. In the figure above, drag either point and note that the line is vertical when they both have the same x-coordinate. A vertical line has no slope.
- 4. the space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet
- 5. drawing Isometric projection is a method for visually representing three-dimensional objects in two dimensions in technical and engineering drawings. It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angle between any two of them is 120 degrees.
- 6. triangle In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°
- 9. a plane figure with eight straight sides and eight angles.
- 13. drawing Oblique projection is a simple type of technical drawing of graphical projection used for producing two-dimensional images of three-dimensional objects.
