Angle of rotation Angle of rotation In mathematics, the angle of rotation is a measurement of the amount, namely the angle, that a figure is rotated about a fixed point, often the center of a circle. A clockwise rotation is considered a negative rotation, so that, for instance, a rotation of 310° (counterclockwise) can also be called a rotation of –50° (since , a full rotation (turn)). A counterclockwise rotation of more than one complete turn is normally measured modulo 360°, meaning that 360° is subtracted off as many times as possible to leave a non-negative measurement less than 360°. For example, the
Simca Type 180 Renault/Peugeot Douvrin engine, but the displacement of the Simca 180 2.2-litre was slightly less. Later, this engine was also turbocharged, for use in the Citroën BX4TC and Peugeot 505 Turbos as the block was stronger than the Peugeot engine. Applications: Simca Type 180 The Type 180 is an automobile straight-4 engine produced in the 1970s. It was an OHC design. These engines (1,639/1,812 cc) were used in the Chrysler 160/180, a car also sold under a multiplicity of other names. Applications: The 1,981 cc Type 180 was most common. It was used in various Chrysler Europe and Simca models. Applications:
