perpendicular

2007-01-06 10:20:28 · answer #1 · answered by      7 · 0 0

In geometry, two lines are considered perpendicular (or orthogonal) if one falls on the other in such a way as to create congruent adjacent angles. The term may be used as a noun or adjective. Thus, referring to Figure 1, the line AB is the perpendicular to CD through the point B.

If a line is perpendicular to another as in Figure 1, all of the angles created by their intersection are called right angles (right angles measure ½π radians, or 90°). Conversely, any lines that meet to form right angles are perpendicular. The line AB does not have to end at B to be considered perpendicular

Those lines would be perpendicular. All the angles would be 90 degrees.

positioned across them as vectors: -3x + y = 3 2x + y = 4 which you will have vectors of <-3 , a million> and <2 , a million>. undergo in ideas, as long as you do now not replace the slope of the lines, you will possibly desire to pass them vertically or horizontally as much as you will like and you will now not replace the attitude between them. Now, we can prepare suitable right here formula: A * B = ||A|| * ||B|| * cos(t) the placement A * B is the dot made out of the vectors ||A|| is the fee of the 1st vector ||B|| is the fee of the 2d vector t is the attitude between them (-3 * 2 + a million * a million) = sqrt((-3)^2 + a million^2) * sqrt(2^2 + a million^2) * cos(t) (-6 + a million) = sqrt(10) * sqrt(5) * cos(t) -5 = 5 * sqrt(2) * cos(t) -a million/sqrt(2) = cos(t) -sqrt(2)/2 = cos(t) t = arccos(-sqrt(2)/2) t = one hundred thirty 5 stages

straight lines (measure 180) that are perpendicular.

Congruent=has the same measure
Adjacent=means that are located along the same vertex ("point of origin" You can almost call them "neighbors"

The only way that both of these conditions can be met, is to have 2 interesecting straight lines (180 degree lines that CROSS each other) that are split identically in half (or in geometry they call it "bisected") to become two perpendicular lines (lines that measure 90 degrees)
