    Study Notes

    Measurement of Angles

    Angles measure the distance between two planes intersecting each other, measured in degrees (°). There are various types of angles categorized according to their degree measurements, including acute angles, obtuse angles, right angles, straight angles, and complete angles. These categories play a significant role in geometry and trigonometry.

    Acute Angles

    An angle is considered acute if its degree measurement is less than 90°, meaning it's smaller than a right angle. In mathematics, there are formulas that help find the complementary angles when given an acute angle. For example, a complementary angle to a 45° angle would be 45° + 90° = 135°.

    Obtuse Angles

    An obtuse angle has a degree measurement that ranges from 90° to 180°, which means it's larger than a right angle but still less than a straight angle. Similar to how acute angles have complementary angles, obtuse angles also have supplementary angles. A supplementary angle to a 135° obtuse angle would be 135° + 180° = 315°.

    Right (Square) Angles

    A right angle measures exactly 90° and represents a square corner. Right angles are often used in architecture and construction due to their stability provided by the structure they create, called right triangles. They are also fundamental in geometry and trigonometry.

    Straight Angles

    Also known as straight lines, straight angles measure exactly 180°. When you connect these angles with a single line, the resulting shape resembles an angular shape.

    Complete Angles

    Complete angles measure 360° and represent the full circle around a central point. In many physical applications, such as rotations in aircraft control systems, complete angles are used rather than individual angles because they easily represent the entire rotation space.

    In conclusion, understanding these different types of angles is crucial in various fields, such as mathematics, engineering, and physics, as they provide a foundation for complex calculations and problem-solving.
