Question

Different between line and line segment
define parrel lines
define angles
what is the right angle and acute angle​

Answer 1

Answer:

1. 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 line segment has two endpoints. It contains these endpoints and all the points of the line between them.

2. In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel. ... A line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are also said to be parallel.

3. the space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet.

4. Acute angles are less than 90 degrees, obtuse angles are more than 90 degrees, and right angles are exactly 90 degrees.

Answer 2

Answer:

(1) a line is endless

line segment has 2 ends

(2) the lines which does not have a common points even when extended evenly on either sides

(3) an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane.

(4) if an angle between 2 rays is equal to 90° then the angle is called as right angle

and if the angle between 2 rays is less than 90° then it is called as acute angle
