Orthogonal and perpendicular are essentially the same thing: When two lines, planes, etc. intersect at a right angle, or 90 degrees, they are orthogonal/perpendicular.
Orthogonal is simply a term used more commonly for vectors, when they have a scalar/inner/dot product of 0, as:
vector u X vector v = (length of vector u) X (length of vector v) X cos @ ,
@ being the angle between the two vectors.
When the scalar product is 0, that is because @ is 90 degrees, and cos 90 = 0. Therefore, the vectors u and v are orthogonal.

How can you determine if two lines are perpendicular?
If the angle formed between the intersecting lines are 90o then the two lines are perpendicular. In 2D coordinate geometry, a perpendicular line has a slope equal to the negative reciprocal of the original line.
ARE Acute angles are formed by perpendicular lines?
No. Perpendicular lines for right angles. That is why they are called perpendicular.
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.
Explain what is the relationship between the equations of perpendicular lines?
The relationship between perpendicular lines lies in there slopes. The slope of one line is the opposite reciprocal of the other. Written mathematically, the lines y=m*x +b and y =(-1/m)*x +c are perpendicular lines (note the y-intercepts do not need to be equal or even related to each other).
What do the angles on perpendicular lines add up to?
The angle between two perpendicular lines is 90 degrees. I am not sure whether you are referring to any other angles, and if yes, which ones.
What are orthogonal lines?
Orthogonal lines are two lines which are perpendicular, i.e. 90 degrees, to each other.
What is perpendicicular lines?
Two lines are perpendicular or orthogonal if they meet at a 90 degree angle.For instance,|__|are two perpendicular lines.
How would you describe two lines that meet together at 90?
Orthogonal lines or perpendicular lines
What are two lines if they intersect to form a right angle?
They are perpendicular lines. A fancier word for that is "orthogonal"
What is the different of a perpendicular lines and intersecting lines?
The only difference between perpendicular lines and intersecting lines is that perpendicular lines create a right angle at the point of intersection.
What do you call the two perpendicular intersecting lines?
Orthogonal. The lines form right angles in a 2-d plane.
What is the difference between a perpendicular lines and intersecting lines?
Intersecting cross each other whereas perpendicular lines cross at right angles.
What is the agular difference between 2 perpendicular lines?
Exactly 90 degrees, that is the definition of perpendicular.
What is the difference between perpendicular lines and perpendicular line segments?
Lines have no end (stretch on forever) Line segments start and end.
What is the difference between perpendicular and intersecting lines?
perpendicular crosses at a right angle, while intersecting lines don't
What are two lines that meet at a right angle?
Two lines that meet at a right angle are called perpendicular.Two lines that meet at a right angle are also called normal.Two lines that meet at a right angle are also called orthogonal.
Are lines e and g perpendicular or parallel?
If two lines (which extend infinitely in each direction) lie on the same plane but never intersect, then the lines are parallel. If the lines somewhere intersect, they are not. And if they intersect at right angles, they are orthogonal, or perpendicular.
