Answer:
True
Step-by-step explanation:
We have the angle of a straight line is 180 degrees at any point.
At any point on a straight line we have two opposite rays on each side of the point.
Hence the given statement i.e.
an angle with a measure of 180 degrees is formed by two opposite rays
is true
(The notion of straight line was introduced by ancient mathematicians to represent straight objects (without curvature) with zero width and depth..)
