In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a ... For example, by counting links, three pieces of chain can be made with ...


So all perpendicular lines are intersecting, but not all intersecting lines are perpendicular. For example, an X is made of two intersecting lines, but the angles  ...


Equivalent lines are what they say, the same lines! Let's say you're given this example: 5x+y=2 and 20x+4y=8 and you have to figure out what kind of line this is.


Perpendicular lines are two or more lines that intersect at a 90-degree angle, like the two lines drawn on this graph, and the x and y axes that orient them.


Parallel and Perpendicular Lines ... Example 1. If two lines intersect and one of the angles formed from the intersection is 90°, what is the measurement of the ...
