what does perpendicular mean?

Answer 1

Perpendicular means that 2 lines make right angles with each other.

Answer 2

Perpendicular in the context of lines means at a right angle to. Two lines are perpendicular if the angle between them is 90 degrees. This concept can be generalized to more abstract settings. For example in an abstract setting where there is this thing called an inner product defined on the objects of the setting two members are perpendicular or orthogonal if the inner product between them is zero. This coincides with the line example if we use the appropriate inner product.

Answer 3

Perpendicular means the line is vertical - straight up. If you were to draw a line on each side from the top down to the bottom at an angle on each side, then you would form two right angled triangles. The angle at the perpendicular line would be right angles on both sides of this line.

Answer 4

Perpendicular is a geometric term usually consisting of 2- 4 lines that are joined together to make one or two 90 degree angles.

Answer 5

perpendicular means:
(1.) Intersecting at or forming right angles
(2.) Being at right angles to the horizontal; vertical.

You know how a graph is? the x and y-axis is two perpendicular lines, intersecting.

Answer 6

Two lines that cross over/through one another and form a 90 degree angle. The angle MUST be 90 degrees or else it is not perpendicular.

Answer 7

perpendicular means that two lines meet to form right angles. If two lines are perpendicular they will resemble a X a right angle in each corner.

Answer 8

Perpendicular lines are two lines that form a right angle at their intersection.

Answer 9

Perpendicular means the two lines cross each other like two streets.

Answer 10

Perpendicular means "at right angles to".
