PARALLEL LINES
Two lines are said to be parallel when they do not meet at any point in a plane. Lines which do not have a common intersection point and never cross path with each other are parallel to each other.
- .The perpendicular distance between the two parallel lines is always constant.
- If two parallel lines are cut by a transversal, then the -
- pairs of corresponding angles are equal.
- pairs of alternate (interior as well as exterior) angles are equal.
- Pairs of Angles
- Lines can either be parallel or intersecting. When two lines meet at a point in a plane, they are known as intersecting lines. If a line intersects two or more lines at distinct points then it is known as a transversal line.
- when a transversal intersects two parallel lines, then pairs of angles are formed, such as:
- Vertically opposite angles
- Alternate exterior angles
- Corresponding angles
- Linear pair
- Alternate interior angles
- when a transversal intersects two parallel lines, then pairs of angles are formed, such as:
- Lines can either be parallel or intersecting. When two lines meet at a point in a plane, they are known as intersecting lines. If a line intersects two or more lines at distinct points then it is known as a transversal line.
- Pairs of Angles
- interior angles on the same side of the transversal are supplementary.
- The distance between parallel lines does not change, it is the same every where.
