What do angles on a straight line equal to?
Angles on a straight line always add up to 180 degrees. This is because a straight line represents a half-turn, and the total measure of angles around a point is 360 degrees. Therefore, the angles on one side of the straight line must sum to half of that total, equating to 180 degrees.
Why are vertical angles used?
because 360 degrees is the total amount of degrees you can get. the degrees are essentially the angle measurement. anything that is 180 degrees is a vertical. so vertical angels are used to indicated a 180degree line.
How many degrees is a vertcal line?
A vertical line is 180 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
Why is a straight line 180 degrees?
A straight line is defined as an angle of 180 degrees because it represents a half-turn around a point. In geometric terms, if you have a point and draw two rays emanating from it in opposite directions, the angle formed between these two rays measures 180 degrees. This is based on the full circle being 360 degrees, where a straight line corresponds to half of that total. Thus, the angle formed by a straight line is precisely half of a complete rotation.
What is the degrees on a line?
There are 180 degrees on a straight line
How many degrees are in a line?
There are 180 degrees in a line.
Why are vertical angles used?

How many degrees are there in a straight line?
There are 180 degrees on a straight line.
How many degrees does a line have?
A perfectly straight line is 180 degrees.
How many degrees is a vertcal line?
A vertical line is 180 degrees.
How many degrees is there in a straght line?
A straight line has 180 degrees.
What is 0.100 of a staight line?
A straight line is 180 degrees, which means .100 of a line is 18 degrees.
How any degrees are n a straight line?
There are no degrees because it is a STRAIGHT 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.
What is the degrees og a straigh line angle?
A straight line has an angle of 180 degrees.
How many degrees is a line?
180 degrees
