Angle Gap or space formed between two line segments, often measured in degrees from a common starting point. Degree Unit for measuring angles, with a full circle containing 360 of these equal divisions. Standard Position Configuration where the initial side of an angle lies along the positive x-axis on a coordinate plane. Initial Side Fixed ray of an angle, always placed along the positive x-axis when drawing in standard position. Terminal Side Ray that represents the end position of an angle after rotation from the initial side. Positive Angle Angle measured by rotating counterclockwise from the initial side on the coordinate plane. Negative Angle Angle measured by rotating clockwise from the initial side on the coordinate plane. Acute Angle Angle whose measure is less than 90 degrees, forming a sharp or narrow gap. Obtuse Angle Angle whose measure is greater than 90 degrees but less than 180 degrees, forming a wide gap. Right Angle Angle measuring exactly 90 degrees, often associated with perpendicular lines. Protractor Instrument used to estimate or measure the size of an angle in degrees. Quadrant One of four regions into which the x and y axes divide the coordinate plane, each spanning 90 degrees. X-Axis Horizontal axis in the coordinate plane, serving as the reference for the initial side of angles. Counterclockwise Direction Movement opposite to the direction of a clock's hands, used for drawing positive angles. Clockwise Direction Movement in the same direction as a clock's hands, used for drawing negative angles.
