To find angles of rotation, you typically use the concept of angular measurement, which can be expressed in degrees or radians. For a full rotation, there are 360 degrees or (2\pi) radians. To calculate the angle of rotation for a specific movement, you can measure the change in position of an object from its initial orientation to its final orientation, often using protractors or trigonometric functions in relation to rotational motion equations. In geometry, the angle can also be determined using the arcsine, arccosine, or arctangent functions based on known side lengths of triangles formed during the rotation.
An octagon may have 1, 2, 4 or 8 angles of rotation.

A full turn rotation is equivalent to 360 degrees. Since a right angle measures 90 degrees, you can fit four right angles in a full turn rotation (360 degrees ÷ 90 degrees = 4). Therefore, there are four right angles in a full turn rotation.

The three transformation in angles are translation , rotation , reflection .
1 complete rotation = 360o 1 right angle = 90o 360o ÷ 90o = 4 There are 4 right angles in 1 complete rotation.

A full rotation = 360°; a right angle = 90° → there are 360° ÷ 90° = 4 right angles in a full turn.
Right angles are ninety degree angles. That is equal to one quarter of a complete rotation.

Angles do not have lengths. They are measured in terms of rotation about the vertex.
The angles of rotation for a regular 20-gon can be determined by dividing 360 degrees by 20, which equals 18 degrees. Therefore, the angles of rotation are multiples of 18 degrees: 0°, 18°, 36°, 54°, 72°, 90°, 108°, 126°, 144°, 162°, 180°, 198°, 216°, 234°, 252°, 270°, 288°, 306°, 324°, and 342°. Each of these angles represents a distinct rotation that maps the 20-gon onto itself.
