what is a line, line segment, linear pair.
Answers
A line is defined as a line of points that extends infinitely in two directions. It has one dimension, length. Points that are on the same line are called collinear points.
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 between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.
. A linear pair is a pair of adjacent, supplementary angles. Adjacent means next to each other, and supplementary means that the measures of the two angles add up to equal 180 degrees

LINE SEGMENT

LINEAR PAIR
Explanation: A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
How to solve
As we have discussed, a linear pair adds up to equal 180 degrees. If you know the measure of one of the two angles, then you can subtract that measure from 180 degrees to get the measure of the other angle. For example, let's say that angle A measures 75 degrees.
How to prove
If two angles form a linear pair, then they are supplementary. In a proof: To say ∠1 + ∠2 = 180, your reason can be “Linear pair postulate,” “linear pairs are supplementary,” or “they form a straight angle.” If a point B lies on segment ����, then ���� = ���� + Ma'am please do mark me Brainliest
