Acute Angle

An acute angle is an angle that measures greater than 0 degrees and less than 90 degrees. In other words, it is an angle that is smaller than a right angle (90 degrees).

Characteristics of Acute Angles:

1. Measure: An acute angle measures between 0 and 90 degrees.
2. Shape: Acute angles are often found in shapes such as triangles and polygons.
3. Representation: Acute angles can be represented using the symbol < for angle measurement.

Examples of Acute Angles:

Here are some examples of acute angles:

• An angle measuring 30 degrees is an acute angle.
• An angle measuring 45 degrees is an acute angle.
• An angle measuring 60 degrees is an acute angle.

How to Identify Acute Angles:

To identify an acute angle, you can use a protractor to measure the angle. If the measurement falls between 0 and 90 degrees, the angle is acute.

Practice Problems:

Now, let's practice identifying acute angles with the following problems:

1. Identify the acute angles in the following figures:

2. Determine if the following angles are acute:
• Angle A: 75 degrees
• Angle B: 110 degrees
• Angle C: 45 degrees

By understanding the characteristics and examples of acute angles, as well as practicing identifying them, you can become proficient in working with these types of angles.

Keep practicing, and you'll master acute angles in no time!
