Identifying and classifying angles:1 classify the angle. Acute,right, obtuse, straight
If the angle measures 90 degrees, it is a right angle.
To classify an angle, you need to look at its measure. Here's how you can identify and classify angles based on their measurements:
1. Acute Angle: An acute angle is an angle that measures less than 90 degrees. To determine if an angle is acute, measure the angle using a protractor. If the measure is less than 90 degrees, it is an acute angle.
2. Right Angle: A right angle is an angle that measures exactly 90 degrees. To determine if an angle is right, measure the angle using a protractor. If the measure is exactly 90 degrees, it is a right angle.
3. Obtuse Angle: An obtuse angle is an angle that measures greater than 90 degrees but less than 180 degrees. To determine if an angle is obtuse, measure the angle using a protractor. If the measure is greater than 90 degrees but less than 180 degrees, it is an obtuse angle.
4. Straight Angle: A straight angle is an angle that measures exactly 180 degrees. To determine if an angle is straight, measure the angle using a protractor. If the measure is exactly 180 degrees, it is a straight angle.
Remember, angles are formed by two rays that share a common endpoint, called the vertex. By measuring the angle, you can accurately classify it as acute, right, obtuse, or straight.
To classify an angle, you need to consider its measure compared to other angles. Here are the classifications for different angle measures:
1. If the angle measures less than 90 degrees, it is called an acute angle.
2. If the angle measures exactly 90 degrees, it is called a right angle.
3. If the angle measures between 90 and 180 degrees, it is called an obtuse angle.
4. If the angle measures exactly 180 degrees, it is called a straight angle.
Please note that these classifications are based on the angle's measure and not its orientation or position.
