If the slopes of two lines are negative reciprocals the lines are perpendicular. true or false?
true (APEX)
If the slopes of two lines are negative reciprocals, the lines are perpendicular. true or false?
true (APEX)
True or false perpendicular lines have opposite slopes?
Not for the usual definition of the word "opposite." The perpendicular of a line having a slope of 2 has a slope of -0.5.
Two lines are perpendicular if they are parallel and cross?
Parallel lines are never perpendicular. Perpendicular lines are co-planar and cross at right angles.
True or false Perpendicular lines form straight angles?
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
If two lines are their slopes are negative reciprocals?
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.
What must be true about the slopes of two perpendicular lines neither of which is vertical?
In that case, the product of the slopes is equal to minus 1.
If the slopes of two lines are negative reciprocals the lines are perpendicular. true or false?
true (APEX)
If the slopes of two lines are negative reciprocals, the lines are perpendicular. true or false?
true (APEX)
Do perpendicular lines have opposite slopes true or false?
No, the slope will be -1
Is it true that two lines with different slopes are perpendicular?
No. Only lines that intersect at 90 degree angles are perpendicular. Any other lines that cross each other are simply intersecting lines.
True or false perpendicular lines have opposite slopes?
Not for the usual definition of the word "opposite." The perpendicular of a line having a slope of 2 has a slope of -0.5.
Can perpendicular lines be intersecting lines?
In Euclidean plane geometry, two lines which are perpendicular not only can but must intersect. (I believe the same is true for elliptic geometry and hyperbolic geometry.)
What is the slope of a line that is perpendicular to a line with a slope of .33?
Perpendicular lines have slopes whose product is -1. As this is always true, if we think of .33 as about 1/3, then the perpendicular line would have a slope of -1/(1/3) which is -3.
Can two lines intersects and be perpendicular?
In Euclidean plane geometry, two lines which are perpendicular not only can but must intersect. (I believe the same is true for elliptic geometry and hyperbolic geometry.)
In every right angle one line segment is perpendicular to another is that true or false?
True. A right angle is 90o so the lines which form it must be mutually perpendicular.
Two lines are perpendicular if they are parallel and cross?
Parallel lines are never perpendicular. Perpendicular lines are co-planar and cross at right angles.
