an angle that is 180* degrees
an acute angle is an angle that is smaller than a straight angle (a straight angle is an angle that is perfect,in other words you can perfectly fit a corner of a papaer into it) :)
If you mean an angle then an angle is formed by two straight lines meeting at a vertex.
By a straight angle I assume you mean an 180° angle, so two angles that form a 180° angle would be called supplementary angles.
A straight angle is 180 degrees.
A straight angle is an angle.
A straight angle is an angle of 180 degrees
An angle that measures 180 degrees is a straight angle, or straight line.Line.
180 degrees -- a straight angle
What does a straight angle measure?
is called a straight angle
A straight angle (180 degrees) makes a perfectly straight line. Any degree below 180 degrees (0-179 degrees) is NOT a straight angle NOR a straight line. straight angle = 180 degrees straight angle = straight line 180 degrees
A 180 Degree angle therefore a straight line.
