What else can I help you with?
Why is there 90 degrees in a right angle?
Because 90 degrees is half of a straight line. A straight line is equal to 180 degrees. 180 divided by 2 = 90.
What line is perpendicular to a horizontal line?
A vertical line at 90 degrees
What is perpaendicular line?
It is a straight line that intersects another line at 90 degrees
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 line cross at a right angle or 90 degrees?
A perpendicular line.
What is a line at 90 degrees to another line?
A line that is at 90 degrees to another line is called a perpendicular line. Perpendicular lines intersect at right angles (90 degrees) forming a "L" shape.
Does 90 degrees west longitude have a name?
No. 90 degrees longitude is not a major line of longitude. Only 0 and 180 degrees longitude, which are the Greenwich Meridian and the International Date Line respectively, are major lines of longitude.
Why is there 90 degrees in a right angle?
Because 90 degrees is half of a straight line. A straight line is equal to 180 degrees. 180 divided by 2 = 90.
What would be the line of longitude for a place that is west of the prime meridianhalfway between the prime meridian and the180 degrees line of longitude?
90 degrees 40 degrees and 90 degrees
What line is perpendicular to a horizontal line?
A vertical line at 90 degrees
What is a nonverticle line?
It is a line that is not at an angle of 90 degrees to the horizontal!
Which term describes lines that intersect at a 90 degree angle?
It is a perpendicular line that intercepts another line at 90 degrees.
What is perpaendicular line?
It is a straight line that intersects another line at 90 degrees
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 six-letter word for a line with angles that is not straight?
Obtuse Yes, For a line set that has an angle greater than 90 degrees, the line set is "OBTUSE". For a line set that has an angle less than 90 degrees, the line set is "ACUTE". For a line set that has an angle equal to 90 degrees, the line set is "RIGHT ANGLE".
What line cross at a right angle or 90 degrees?
A perpendicular line.
Can a perpendicular line be 88 degrees?
A perpendicular line is 90 degrees. Anything less or more is not perpendicular.
