Geometry - Perpendicular Lines


Expert: Azeem Hussain - 6/30/2009

Question
if the perpendicular lines doesn't form a right angle, can it still be considered perpendicular? like what if the 2 intersecting lines formed obtuse and acute angle? i've read about perpendicular lines and all of them says that it forms right angles. please explain...thanks in advance

Answer
Hi Anee,

Perpendicular lines are at right angles, 90 degrees, ALWAYS.  This is their definition.  Two intersecting lines that form obtuse and acute angles are NOT perpendicular lines.

It is of interest to note that the lines can be perpendicular without actually intersecting.  See below:

Although the vertical line does not intersect the horizontal line, they are still perpendicular to one another.  If you were to extend the lines, they would meet forming a right angle.

Thanks for asking,
Azeem
