A line has one dimension.
You can figure out how many dimensions a shape has by asking yourself how many coordinates you need to find a point within that shape. The points on a line can be described by just one number each, so it has one dimension. The points on a plane need two numbers to describe them (x and y coordinates), so a plane has two dimensions.

A finite part of a line?
Technically, in geometry, there is no such thing. By definition, a line is infinite. A "line segment" is a finite portion of a line. In everyday speech, people might sometimes refer to a line segment as a finite line. But if you said this on a math test, you would fail the test.
What is the mid point?
The midpoint is the point that divides a line segment into two equal parts. It is equidistant from the endpoints of the line segment.
How does a line segment look like?
A line segment is a straight path that connects two points. It is finite in length and does not extend infinitely in both directions, unlike a line. A line segment is commonly represented by a line with a start point and an end point.
The distance from a point C to the line AB is the length of the segment from C to AB?
That is correct. The distance from a point C to a line AB is the length of the perpendicular segment drawn from point C to line AB. This forms a right angle, creating a right triangle with the segment as the hypotenuse. The length of this perpendicular segment is the shortest distance from the point to the line.
What is a aligned dimension?
An aligned dimension is a type of dimension in drafting and design that is placed parallel to the dimension line. It is used to specify the distance or size of an object in a drawing accurately. This type of dimension is common in engineering and architectural drawings.
