An angle on the coordinate plane is in standard form when the vertex is on the origin and one ray lies on the positive x axis The ray on the x axis is called the The other ray is called the x Counterclockwise rotations result in angle measures DEGREES 90 y 180 0 360 0 36 0 270 Clockwise rotations result in angle measures The most common unit of measure for angles is the A degree is

measure based on arc length One radian is defined as the measure of the angle formed when the radius is equivalent to the length of the intercepted arc Recall that the circumference of a circle is 2 r
