it is a straight line
A 0 degree is a angle called a straight line but 180 degree is a straight line too. So cool yeah
A straight line
180 degree angle.
A 180 Degree angle therefore a straight line.
A line which rotates through an angle of 10 degree with the positive side of the x-axis of the Cartesian plane is called a 10 degree angle.
A 90-degree angle is a right angle.
50° angle measure 50° m?= 50° replace the question mark with the line's name, or what the line is called.
if the two line intersect at 90 degree then these are called perpendicular lines
180 degree angle
A straight line is equal to a 180 degree angle.
A 140 degree angle is about half way between a 90 degree angle, which has lines that are perpendicular to each other, and a 180 degree angle, which is a straight line. A 140 degree angle is an obtuse angle which has a line a little over half way between the 90 degree and 180 degree angles.
