When the alternate interior angles are equal
storyofmathematics.com
- Solution: The two lines are parallel as they meet one of the properties of parallel lines “when the alternate interior angles are equal, the lines are parallel”. ∠ a is equal to ∠ c, and both of these are alternate interior angles. This proves that the two lines are parallel.

Lines are parallel if they are always the same distance apart (called "equidistant"), and will never meet. Just remember: Always the same distance apart and never touching. The red line is parallel to the blue line in each of these examples: Parallel lines also point in the same direction. Parallel lines have so much in common.

Sep 5, 2021 · \(\overleftrightarrow{AB} || \overleftrightarrow{CD}\) since the arrows indicate parallel lines. \(x^{\circ} = 40^{\circ}\) because alternate interior angles of parallel lines are equal. \(y^{\circ} = z^{\circ} = 180^{\circ} - 40^{\circ} = 140^{\circ}\). Answer: \(x = 40, y = 140, z = 140\).
Parallel lines are lines in a plane which do not intersect. Like adjacent lanes on a straight highway, two parallel lines face in the same direction, continuing on and on and never meeting each other. In the figure in the first section below, the two lines \(\overleftrightarrow{AB}\) and \(\overleftrightarrow{CD}\) are parallel.

Parallel lines are two or more than two lines that are always parallel to each other, and they lie on the same plane. No matter how long parallel lines are extended, they never meet. Parallel lines and intersecting linesare opposite each other. Parallel Lines are the lines that never meet or have any chance of meeting. In the diagram, parallel line...
Parallel Lines Symbol
Parallel lines symbol is denoted as || as they never meet each other or intersect each other no matter how long they are extended. So, the symbol used to denote the parallel lines is ||. For instance, if AB is parallel to XY, we write it as AB || XY.
The slope is a measurement to determine the extent line is oriented to an axis. In general, we define slope as the tangent of the angle between the X-axis and a line. If the angle between x-axis and a given line is θ, then
When a line intersects two parallel lines or lines that are not parallel, it is called a transversal. Due to the transversal line, many relations among the pair of anglesare created. They can be supplementary or congruent angles. Suppose the given diagram is creating angles a, b, c, d, and p, q, r, s due to the transversal. These eight separate ang...
Angles are created due to transversal and parallel lines 1 and 2. Let’s take a look at the properties these angles showcase: 1. Alternate Interior Angles:Alternate interior angles are created by the transversal on parallel lines, and they are equal in nature. For example, here, ∠c = ∠p and ∠d = ∠q. The best way to identify the alternate interior an...
Below are some of the important properties of parallel lines: 1. Two or more lines can be considered parallel if, even on extending the lines, there is no chance that the lines will meet or cut each other (intersect each other). 2. Parallel lines have the special property of maintaining the same slope. 3. The distance between Parallel lines always ...
When two or more parallel lines are cut by a transversal, then the angle made by the transversal with the parallel lines shows some distinct properties: 1. Parallel lines, when cut by a transversal, have equal alternate interior angles. 2. Parallel lines, when cut by a transversal, have equal alternate exterior angles. 3. Parallel lines, when cut b...
In the parallel line’s equation, the slope of the lines is always the same. The equation for a straight line is in slope-intercept form, that is, y = mx + c, where m is the slope. For parallel lines, m will be the same; however, the intercept is not the same. For example, y = 3x + 8 and y = 3x + 2 are parallel to each other. Therefore, in the paral...
Below are the axioms and theorems of parallel lines: Corresponding Angle Axiom: Corresponding angles are equal to each other. In corresponding angles axioms, it is said that if the reverse of the property is true, that is, if the reason of the property is true, the assertion must be true as well. The corresponding angles axiom states that if the co...
In the context of systems of linear equations, if two lines are parallel, it means they have the same slope but different y-intercepts. When you solve such a system, you’ll find that there are either infinitely many solutions (if the lines coincide) or no solution (if the lines are distinct and parallel). Therefore, parallel lines lead to a consist...
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.
the pair of interior angles on the same side of traversals is supplementary, then the two straight lines are parallel. the pair of corresponding angles are equal, then the two straight lines are parallel to each other.
If two lines are parallel to the same line, they are parallel to each other. Parallel lines cut by a transversal have the following properties: Corresponding angles are congruent.
