What is a line that starts at a point and extends infinitely?
Chapter 7 Vocabulary
|ray||a part of a line that starts at one endpoint and extends forever|
|line segment||a part of a line that extends from one endpoint to another|
|plane||a perfectly flat surface that extends infinitely in all directions|
|congruent||having the same shape and size|
What is part of a line that has one endpoint and extends in one direction without ending?
A ray is part of a line. It has one endpoint and extends without end in one direction. It is represented with one endpoint and one point on the line. It is named using the endpoint first.
What is the term for a part of a line with two end points?
A line segment is part of a line that has two endpoints and is finite in length.
What is part of a line with two endpoints?
A line segment is part of a line that has two endpoints and is finite in length. A ray is a line segment that extends indefinitely in one direction.
What is a line that has only one endpoint?
A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the ray (for example, →BA ).
What do you call the intersection of two lines?
The point where the lines intersect is called the point of intersection. If the angles produced are all right angles, the lines are called perpendicular lines. If two lines never intersect, they are called parallel lines.
What is 1 dimensional and have infinite length?
A line is a one-dimensional figure that is made up of an infinite number of individual points placed side by side. In geometry all lines are assumed to be straight; if they bend they are called a curve. A line continues infinitely in two directions.
Which is extended in two direction?
A line is defined as a line of points that extends infinitely in two directions which is shown by the arrowheads. A ray is named by its endpoint and by another point on the line. The angle that is formed by two rays that have the same endpoint is called the vertex.
Which of the following does extend indefinitely without ending?
A line has one dimension. It is represented by a line with two arrowheads, but it extends without end.
