These lines are parallel, because a pair of Corresponding Angles are equal. These lines are not parallel, because a pair of Consecutive Interior Angles do not add up to 180° (81° + 101° =182°) These lines are parallel, because a pair of Alternate Interior Angles are equal.

Solution. since the arrows indicate parallel lines. because alternate interior angles of parallel lines are equal. . Answer: . Corresponding angles of two lines are two angles which are on the same side of the two lines and the same side of the transversal, In Figure , and are corresponding angles of lines and .
Parallel lines are seen in many common 2D shapes. For example, Each side of a square is made of a line segment that is part of a line. The opposite sides of a square are parallel. There are also many examples of parallel lines in real life. For example, The lines that pass by the sides of a table top are parallel.
Parallel lines. Two or more lines that lie in the same plane and never intersect each other are known as parallel lines. They are equidistant from each other and have the same slope. Let us learn more about parallel lines, the properties of parallel lines and the angles that are formed when parallel lines are cut by a transversal.

In the figure below, line “AB” is parallel to the line “CD”. The perpendicular distance is always the same between two parallel lines. Sides of various shapes are parallel to each other. In the rectanglegiven below, the single arrow lines are parallel to each other, and similarly, the double arrow lines are also parallel to each other. Parallel lin...
A transversal is a line that intersects two parallel lines (or lines on a plane) at different intersecting points, forming angles.
Parallel lines can be easily identified using the following fundamental properties and characteristics: 1. They are always straight lines with an equal distance between each other. 2. They are coplanar lines. 3. They never intersect, no matter how far you try to extend them in any given direction. 4. If there is a transversal line that intersects t...
Linear equations are generally described by the slope-intercept represented by the equation y=mx+b. Where “m” is the slope, “b” is the y-intercept, and y and x are variables. The value of “m” determines the slope and indicates the steep slope of the line. Note that the slopes of the two parallel lines are always the same. For example, if the slope ...
Example 1: Find out which lines are parallel to each other in the given figure. Solution: All the three lines with arrows passing through them are parallel to each other, which means: a || b || c Lines with the double arrows, i.e., line d and e are transversals of lines a, b, and c, but they are parallel to each other. So, we can say that d || e Ex...
Example 8. If ∠ 1 ∘ and ∠ 8 ∘ are equal, show that ∠ 4 ∘ and ∠ 5 ∘ are equal as well. Solution. The angles ∠ 1 ∘ and ∠ 8 ∘ are a pair of alternate exterior angles and are equal. Recall that two lines are parallel if its pair of alternate exterior angles are equals. Hence, A B ― and C D ― are parallel lines.

9y = − 6x + 30. y = - 6 9x + 30 9. Hence the slope of the line is - 6 9, which can be simplified to - 2 3. Since the slope of the second line is the same as the slope of the first line, both lines are parallel. Example 4: Find the equation of a line parallel to y = 5x + 8 and passes through the point (2, 6). Solution:
