Study Notes

Classification of Angles

Zero Angle: Formed when two arms of an angle overlap completely, measuring 0 degrees.
Acute Angle: Defined as an angle that measures more than 0 degrees but less than 90 degrees.
Right Angle: A specific angle that measures exactly 90 degrees, often seen in corners of squares and rectangles.
Obtuse Angle: Measures more than 90 degrees but less than 180 degrees, illustrating angles greater than a right angle.
Straight Angle: Represents a straight line, measuring exactly 180 degrees.
Reflex Angle: An angle measuring more than 180 degrees but less than 360 degrees, showcasing a larger turn.
Complete Angle: Occurs when one arm of the angle makes a full rotation and overlaps the other arm again, measuring 360 degrees.
