What else can I help you with?
Where is the altitude of a right triangle?
'altitude' or perpendicular. If on line is the base (horizontal) line, then the line that is a 90 degrees to it is the perpendicular/altitude.
What is a nonverticle line?
It is a line that is not at an angle of 90 degrees to the horizontal!
What line is perpendicular to a horizontal line?
A vertical line at 90 degrees
What is a level called if it is vertical?
A line 90 degrees from horizontal is a plumb line.
How can you construct 135 degree angle only with a scale and compasses?
Construct a perpendicular line that intersects a horizontal line at 90 degrees and then bisect the vertical line with the horizontal line will give an obtuse angle of 135 degrees because 90 degrees+45 degrees = 135 degrees
What is a line perpendicular to the horizontal called?
A right angle which is 90 degrees
What is an angle formed when a vertical line intersects a horizontal line?
Right angles (90 degrees) will be formed.
What do vertical angles add up to?
A vertical angle is perpendicular to a horizontal base and equals 90 degrees
What way does a vertical line go?
It goes up like this ----> l
What is meanning of x-axis?
It is the horizontal number line that intersects the y axis at 90 degrees on the Cartesian plane
What does x-axis mean?
It's the horizontal line on the Cartesian plane that meets the y-axis at the origin at 90 degrees.
What are not horizontal and vertical lines?
Any line that is not running exactly straight up and down is not vertical. Any line that is not running exactly flat, left to right is not horizontal. Vertical and horizontal lines are always at 90 degrees to each other.
