A straight angle.
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 line passing through the midpoint of a 90-degree angle is called the angle bisector. It divides the angle into two equal angles of 45 degrees. The angle bisector has important properties in geometry, such as being equidistant from the sides of the 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.
