Arrowheads are used to indicate the end of a dimension line or leader.

Why does a line have arrowheads at both ends?
There are arrows on both sides. It indicates it can go further on both sides without end. This is called line. A line goes without end in both directions.
Which of the following that represented with straight line with two arrowheads to indicate that the line extends without end in two directions?
A line extends in one dimension. It is usually represented by a straight line with two arrowheads to indicate that the line extends without end in two directions, and is named by two points on the line or a lowercase script letter. A plane extends in two dimensions.
How many end point has a line segment?
two endpoints
A line segment has two endpoints.
Which line on a drawing should be the thickest?
The direction of the cutting line is shown with a line called a cutting plane lineHeavy dashed line that shows a theoretical cut through an object.. This is the thickest line that may appear on a drawing.
What is indicated by arrowheads on a line quizlet?
Arrowheads are used to indicate the end of a dimension line or leader.
What is usually represented by a straight line with no arrowheads to indicate that it has a fixed length?
A line segment is usually represented by a straight line with no arrowheads to indicate that it has a fixed length.
What has one dimension it is represented by a line with two arrowheads but it extends without end?
Line A line has one dimension. It is represented by a line with two arrowheads, but it extends without end. Through any two points, there is exactly one line.
What has a definite length?
Line Segment has a definite length. A line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints is called a line segment.
Are points that lie on the same plane?
coplanar: when points or lines lie on the same plane, they are considered coplanar.
When three points lie on a line they are said to be?
Three or more points that lie on the same line are collinear points . Example : The points A , B and C lie on the line m .
Does the dotted line represent?
The dashed line often represents something that is in a temporary or transitional state. In this context, it is used as a placeholder, indicating there is more to come.
What type of line has 0.35 to 0.45 mm thickness?
Dashed and medium thick (0.35 – 0.45 mm).
What is the type of line used for line A?
What is the type of line used for line a? Explanation: Continuous thin straight lines are used to denote the dimensions of the object. Thin lines are used so as to distinguish between outline and the dimension line.
What do call a line with an arrowhead in one end used to indicate the measurement of the object?
extension lines
Dimension lines are thin and are used to show the actual size of an object. There are arrowheads at both end that terminate at the extension lines. Extension lines are also thin lines, showing the limits of dimensions.
Has an arrowhead on each end?
Arrowheads are placed at each end of dimension lines, on leader lines, etc. Correctly made, arrows are about 1/8” to 3/16” in length, and are about three times as long as they are wide.
What would represent a plane in the real world?
Examples of a plane would be: a desktop, the chalkboard/whiteboard, a piece of paper, a TV screen, window, wall or a door.
What are points that lie on the same line?
Points that lie on the same line are called collinear points. If there is no line on which all of the points lie, then they are noncollinear points.
What has a location but no dimension?
a point indicates a location (or position) in space. a point has no dimension (actual size). a point has no length, no width, and no height (thickness).They simply represent a location.
Who has no dimension?
point
A point has no dimensions. A point really has no size at all!
What is an exact location in space?
Point. A point is an exact location in space. A point is denoted by a dot. A point has no size.
