Answer:
Straight angle
Step-by-step explanation:
an angle with a 180 measure is a straight angle
an angle with a more than 90 but less than 180 degree measure is obtuse
an angle with a 90 degree measure is a right angle
an angle with a less than 90 degree measure is acute
and a angle with a more than 180 but less than 360 degree measure is a reflex angle
