Question
Classify each angle as acute, obtuse, right or straight
- Right angle
- Acute angle
- Obtuse angle
- Straight angle
Hint:
General representation of the obtuse angle.
The correct answer is: Obtuse angle
* An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
* The symbol ∠ represents an angle. Angles are measured in degrees (°) using a protractor.
*Based on their measurements, here are the different types of angles:
=>An acute angle measures less than 90° at the vertex.
=>An obtuse angle is between 90° and 180°.
=>A right angle precisely measures 90° at the vertex.
=>An angle measuring exactly 180° is a straight angle.
=>A reflex angle measures between 180°- 360°.
=>A complete angle measures 360°.
Given That:
>>>In the given figure the angle between the first ray and the second ray is greater than 90 degreea and less than 180 degrees.
>>These types of angles are called as an obtuse angles.
<<<Therefore, the angle measured is an obtuse angle.
Step 1:
Given angle is more than 90 and less than 180
Step 2:
So, the given angle is an obtuse angle
>>>Hence, the angle of measurement is an obtuse angle.
