Question

determine if the angle described is acute, obtuse, right orstraight. 68° 177° 131° 15° 162° 32° 0° 35° do not write on this paper. number 1 to 20 in your notes and write the described angle.

Explanation:

Step1: Recall angle - type definitions

An acute angle is between 0° and 90°, an obtuse angle is between 90° and 180°, a right - angle is 90°, and a straight - angle is 180°.

Step2: Classify 68°

Since 0° < 68° < 90°, it is an acute angle.

Step3: Classify 177°

Since 90° < 177° < 180°, it is an obtuse angle.

Step4: Classify 131°

Since 90° < 131° < 180°, it is an obtuse angle.

Step5: Classify 15°

Since 0° < 15° < 90°, it is an acute angle.

Step6: Classify 162°

Since 90° < 162° < 180°, it is an obtuse angle.

Step7: Classify 32°

Since 0° < 32° < 90°, it is an acute angle.

Step8: Classify 0°

It is not an acute, obtuse, right or straight angle in the typical sense, but for the given classification, it is not one of the main types.

Step9: Classify 35°

Since 0° < 35° < 90°, it is an acute angle.

Answer:

1. Acute
2. Obtuse
3. Obtuse
4. Acute
5. Obtuse
6. Acute
7. Not one of the main types
8. Acute
