If two parallel lines are cut by a transversal, then corresponding angles are congruent. If two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel.

If two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel.

Definition: A line that cuts across two or more (usually parallel) lines. In the figure below, the line AB is a transversal. It cuts across the parallel lines PQ and RS. If it crosses the parallel lines at right angles it is called a perpendicular transversal.

If two lines are cut by a transversal and the alternate exterior angles are equal, then the two lines are parallel. Angles can be equal or congruent; you can replace the word “equal” in both theorems with “congruent” without affecting the theorem. So if ∠B and ∠L are equal (or congruent), the lines are parallel.

Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an “inconsistent” system of equations, and it has no solution.

The first is if the corresponding angles, the angles that are on the same corner at each intersection, are equal, then the lines are parallel. The second is if the alternate interior angles, the angles that are on opposite sides of the transversal and inside the parallel lines, are equal, then the lines are parallel.

The three parallel lines theorem is another theorem that provides a ratio between line segments created by a transversal of parallel lines, similar to the Intercept Theorem.

a≢bmeans that “a is not identical to b” or “ais not, by definition, equal to b.” a≢bmeans that “a is not identical to b” or “ais not, by definition, equal to b.” For a more nuanced answer, context is important. For example, p≡q may used to express the fact that p,q are logicallyequivalent.

The hamburger menu (which doesn’t come with a side order of fries) is the three horizontal lines you see now at the top of many screens, either on the far left or the far right. It’s an icon, actually. By touching, tapping or clicking on the icon, it opens up a side menu with a selection of options or additional pages.

Three bold, thick, black lines that wrap around the arm or leg, or any other body part, is often an expression of symmetry and the uniformity that is found in nature. In other cases, the three lines can be symbolic for three significant people, periods of time, events, or any other place or idea.

Microsoft calls this the “nav bar.” The icon at the far left (nine dots) is the app launcher, where you can access the various parts of Office 365, including Outlook mail, calendar, people, OneDrive, Office Online apps, and more.

• ⋮- that character is also called “vertical ellipsis” – Dan Dascalescu Jul 18 ’17 at 0:32.
• the three vertical dots are called ActionMenu in Android and the icon in Flutter is more_vert – Mahesh Jamdade Aug 20 ’19 at 12:04.

Word also has a special shortcut for ellipsis Ctrl + Alt + . That shortcut or AutoCorrect insert the ellipsis symbol from Unicode, officially called Horizontal Ellipsis.

What does 4 dots in a text mean? It means “we’ll see, end of discussion for now.”

Two dots is an informal and cute way of implying there is something else to say, except philosophically you don’t need to say it at that moment, so it’s more of a short-cut, and yes two dots is quicker that three since the latter means something else, formally any-way.
