Study Notes
Types of Angles
- Acute Angle: Defined as an angle that measures less than 90 degrees.
- Right Angle: Measures exactly 90 degrees and is perpendicular.
- Obtuse Angle: An angle that measures more than 90 degrees but less than 180 degrees.
Angle Measurements
- An angle measuring 75 degrees is classified as acute, since it is less than 90 degrees.
- An angle measuring 135 degrees is classified as obtuse, as it exceeds 90 degrees.
Identifying Angles
- An angle measuring 60 degrees is an example of an acute angle.
- A measurement of 95 degrees identifies an angle as obtuse.
- An angle measuring 120 degrees falls into the obtuse category.
True or False Statements
- An acute angle is never larger than a right angle; therefore, the statement "An acute angle is larger than a right angle" is false.
Summary
- Understanding angle classifications is crucial: acute (<90°), right (=90°), and obtuse (>90° and <180°) define their characteristics effectively.
