The classifications of the angles in the image:
Angle AOB: Straight angle (180 degrees)
Angle AOD: Reflex angle (greater than 180 degrees)
Angle BOD: Obtuse angle (greater than 90 degrees and less than 180 degrees)
Angle COD: Acute angle (greater than 0 degrees and less than 90 degrees)
To classify an angle, you need to measure its angle size. You can use a protractor to measure the angle size in degrees.
Here are the instructions on how to classify each of the angles in the image:
Find the vertex of the angle. The vertex is the point where the two sides of the angle meet.
Place the protractor at the vertex of the angle. Make sure that the zero mark on the protractor is aligned with one side of the angle.
Trace the other side of the angle with the protractor. The angle size is the number of degrees that the needle of the protractor points to.
Here are the classifications of the angles in the image:
Angle AOB: Straight angle (180 degrees)
Angle AOD: Reflex angle (greater than 180 degrees)
Angle BOD: Obtuse angle (greater than 90 degrees and less than 180 degrees)
Angle COD: Acute angle (greater than 0 degrees and less than 90 degrees)
Complete question:
Classify each of the following angles:
(i)/_AOB
(ii) /_AOD
(iii)/_BOD
(iv) /_COD
just tell instructions that how to classify.
