Which term names an angle that lies on a straight line?

Explanation:
An angle on a straight line is called a straight angle. This happens when the two rays share an endpoint and go in opposite directions along the same line, forming a 180-degree turn along that line. The straight angle is the name for this kind of angle. The other terms don’t fit: an acute angle is any angle smaller than 90 degrees, which does not lie along a straight line; a plot is something you graph or map out, not an angle; a label is just a name for a figure, not a type of angle.
