## How many perpendicular lines does a right triangle have?

two perpendicular lines

hypotenuse

## How many perpendicular lines can be drawn to a line?

Answer: An infinite number of lines perpendicular to any given line Through a specific point on a line, though, there exists only one perpendicular line. Likewise, given a line and a point not on that line, there is only one perpendicular line through the noncolinear point.

## How many perpendicular bisectors can be drawn to a line?

one perpendicular bisector

## Can a line be perpendicular to infinitely many lines?

Just as there are infinitely lines parallel to any given line, there are infinitely many line perpendicular to a given line.

## Why are two lines perpendicular to a third line not parallel?

In relationship to parallel lines If two lines (a and b) are both perpendicular to a third line (c), all of the angles formed along the third line are right angles. Therefore, in Euclidean geometry, any two lines that are both perpendicular to a third line are parallel to each other, because of the parallel postulate.

## Are two lines perpendicular to a third line parallel?

Two lines perpendicular to a third line are parallel. Two planes parallel to a third plane are parallel.

## What are two lines perpendicular to the same plane?

In a plane, if two lines are perpendicular to the same line, they are parallel. In space, if two lines are perpendicular to the same line, they are parallel.

## Is a line perpendicular to itself?

(i) No line is perpendicular to itself.

## What are the conditions for two vectors to be parallel 2 perpendicular to each other?

Two vectors A and B are parallel if and only if they are scalar multiples of one another. A = k B , k is a constant not equal to zero. Two vectors A and B are perpendicular if and only if their scalar product is equal to zero.

## How do you know if parametric equations are parallel?

we can choose two points on each line (depending on how the lines and equations are presented), then for each pair of points, subtract the coordinates to get the displacement vector. If the two displacement or direction vectors are multiples of each other, the lines were parallel.
