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
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 perpaendicular line?
It is a straight line that intersects another line at 90 degrees
An angle of 180 degree is called what?
a flat line.90 degrees is a straight corner, L180 degrees is a straight line, l270 degrees is a straight corner but opposite of 90 degrees, L360 degrees is a straight line that have turned all the way round, l
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.
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
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 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 is the name of the latitude line 180 degrees north and south of the prime meridian?
the Prime meridian is a longitudinal line at 0 degrees and runs north and south. There is no 180 degrees below or above it. 180 degrees latitude doesn't exist. Latitudes range from 90 degrees south, at the south pole, through zero, at the equator, to 90 degrees north, at the north pole. There are no latitude numbers greater than 90.
Can a perpendicular line be 88 degrees?
A perpendicular line is 90 degrees. Anything less or more is not perpendicular.
What is another name for a 45 degree angle?
There isn't a specific name for 45 degrees, like when 90 degree angle is called a "right angle". However, there is a general term for any angle less than 90 degrees - "acute angle". Here's a full list: < 90 degrees = acute 90 degrees = right angle between 90 & 180 degrees = obtuse 180 degrees = straight line between 180 & 360 degrees = reflex 360 deg = revolution (because it turns in a complete circle)
How many degrees is a perpendicular line?
Perpendicular lines meet at 90 degrees
What name has been given to the line that runs abut 60 degrees?
An Acute Angle.. An acute angle is any angle between 0 and 90 degrees, then of course you have right angle at 90 degree, etc
If a line is a perpendicular bisector to a line segment what angle do they intersect at?
90 degrees
What is a level called if it is vertical?
A line 90 degrees from horizontal is a plumb line.
What are plumbing tees?
A T in the line so that you can add a line 90 degrees to the main line.
