A straight angle is by definition 180°.
An angle that forms a straight line has an angular measure of 180 degrees.
An angle of 180 degrees is a straight line.
An angle of 180° is a straight line.
The only angle that can measure 180 degrees is a straight line.
Lines are not measured in degress, however there is a straight angle which measures 180 degrees.
An angle that forms a straight line has an angular measure of 180 degrees.
An angle of 180 degrees is a straight line.
It is called a straight angle.
An angle of 180° is a straight line.
An angle with 180 degrees is a straight line, so it's known as a straight angle.
The only angle that can measure 180 degrees is a straight line.
Lines are not measured in degress, however there is a straight angle which measures 180 degrees.
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
An obtuse angle is any angle which measures between 90 degrees (that is, a right angle), and 180 degrees (that is, a straight line).
A straight angle is an angle that measures 180 degrees and is drawn as a straight line. A straight angle is composed of two right angles whose measures are 90 degrees each.
An angle of 180 degrees is a straight angle, a straight line.
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
