semicircle
No, because all three angles need to add to exactly 180 degrees
As 273° is greater than 180° it is a reflex angle.
No. Only the sum of the measures of the angles of a triangle equal to 180 degrees; in the case of a quadrilateral it amounts to 360 degrees.
180 - x degrees.
An angle that measures greater than 90 degrees but less than 180 degrees is an obtuse angle.
Half the circumference of a circle has an arc of 180 degrees
It is half the circumference of a circle that has an arc of 180 degrees
Supplementary angles add up to 180 degrees
A straight angle measures 180 degrees.
A straight angle measures 180 degrees.
an angle that measures exactly 180 degrees
That is a straight angle.
an angle that measures exactly 180 degrees
Obtuse. Any angle measuring greater than 90 degrees but less than 180 is considered obtuse. An acute angle is any angle measuring between 0 and 90 degrees. A right angle is an angle measuring exactly 90 degrees while a straight angle measures exactly 180 degrees.
No, because all three angles need to add to exactly 180 degrees
