What is the instrument used to measurea angle?
A protractor measures degrees: 90, 80, 120 etc. If something is 90 degrees it is at a right angle
An exterior angle at the base of an isosceles triangle measures 130 find the measure of the vertex angle?
80 degrees.
Is 80 degrees obtuse?
No, 80 degrees is not obtuse; it is classified as an acute angle. An obtuse angle is defined as one that measures more than 90 degrees but less than 180 degrees. Since 80 degrees is less than 90 degrees, it falls into the acute category.
An angle that measures 210 degrees is?
An angle that measures 210 degrees is a reflex angle.
What If a triangle has angles whose measures are 55 and 80 what is the measure of the third angle?
The 3rd angle is: 180-55-80 = 45 degrees
How much is an acute angle?
Any angle which is less than 90 degrees is an acute angle.
What is the reference angle of 80 degrees?
The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. For an angle of 80 degrees, since it is already in the first quadrant and less than 90 degrees, the reference angle is simply 80 degrees itself. Thus, the reference angle of 80 degrees is 80 degrees.
