Thereof, is a 180 degree angle a straight line?
A straight angle is 180degrees.
Also Know, how many degrees is a horizontal line? Horizontal angles are usually expressed indegrees . A full circle is divided into 360 degrees ,abbreviated as 360° . Note from the figure these two particularvalues: a 90° angle , called a right angle, is made of twoperpendicular lines.
Similarly, it is asked, what is an 180 degree angle?
right angle-an 90 degree angle. obtuseangle-an angle between 90 and 180 degrees.straight angle-a 180 degree angle.
What kind of angle is a straight line?
A straight angle is exactly 180 degrees and iscomposed of exactly one line with no changes in vector. Anyline through it will form four angles (two on eitherside of the straight angle). Additionally, any twocontiguous angles must be supplementary or equal 180degrees.
