What object represents a line?
The following can represent a line: intersection of a side wall and ceiling, laser, electric wire edge of a table.
Which object best represents a line?
What object represents a point?
A point is the most fundamental object in geometry. It is represented by a dot and named by a capital letter.
How do you represent a line in geometry?
When we draw lines in geometry, we use an arrow at each end to show that it extends infinitely.
- A line can be named either using two points on the line (for example, ↔AB ) or simply by a letter, usually lowercase (for example, line m ).
- A segment is named by its two endpoints, for example, ¯AB .
Which of the following is a characteristics of a line?
The physical characteristics of line are many. Lines may be short or long, thin or thick, straight or curved, direct or meandering, zigzag or serpentine, distinct or blurred.
What is the best definition of a line segment?
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints.
Are points on the same line?
Points lie on the same line, if they are collinear. If two lines are parallel, then they never intersect.
What makes a line a line?
A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. Euclid defined a line as a “breadthless length,” and a straight line as a line that “lies evenly with the points on itself” (Kline 1956, Dunham 1990). Consider first lines in a two-dimensional plane.
What are three characteristics of a line?
What are the quality of lines?
Line quality is also called line weight and simply put, refers to the thickness or thinness of the line. Lines may become wider or thicker in areas where the object itself is thicker.
What is line segment example?
A scale.: A length measuring instrument, usually 15 cm or 30 cm in length, is a good example of a line segment. 4. The edges of a book / paper / black board.: All these shapes are usually rectangles and their edges are straight line segments. 5.
Which is the best definition of an object line?
Object Line A visible line, or object line is a thick continuous line, used to outline the visible edges or contours of an object.
What is a lined graph used for?
Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group. . . . a Pie Chart.
When to use center lines and dimension lines?
Center lines are used to indicate the centers of holes, arcs, and symmetrical objects. They are very thin (size), long-short-long kinds of lines. Dimension lines are thin and are used to show the actual size of an object.
What’s the difference between visible and hidden lines?
A visible line, or object line is a thick continuous line, used to outline the visible edges or contours of an object. A hidden line, also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen.
