The X,Y equations listed are for CW rotations but the calculator tells you to define CCW as positive. The vector (1,0) rotated +90 deg CCW is (0,1). This calculator will tell you it's (0,-1) when you rotate by +90 deg and (0,1) when. The angle of rotation is a measurement in mathematics of the amount, or angle, that a figure is rotated around a given point, usually the centre of a circle. A clockwise rotation is regarded as a negatives motion, hence a 310° (counterclockwise) rotation is also known as a –50° rotation (because 310° + 50° = 360°, a full rotation (turn)). The images B and C are generated by rotating the original image A. When we look at the above images of equilateral triangle, it fits on to itself 3 times during a full rotation of 360 degrees. Hence, an equilateral triangle has rotational symmetry of order 3. Step-by-step explanation: image don't make this page.

Angles and Triangles - Prakash Kumar Sekar Prakash Kumar S 2. Angles An angle is the amount of rotation between two straight lines. Angles may be measured either in degrees or in radians. If a circle is divided into 360 equal parts, then each part is called 1 degree and is written as 1 1 revolution = 360 Prakash Kumar S.

The angle of rotation is the amount of rotation and is the angular analog of distance. The angle of rotation Δ θ is the arc length divided by the radius of curvature. Δ θ = Δ s r. The angle of rotation is often measured by using a unit called the radian. (Radians are actually dimensionless, because a radian is defined as the ratio of two. So, the angle of rotation for a square is 90 degrees. In the same way, a regular hexagon has an angle of symmetry as 60 degrees, a regular pentagon has 72 degrees, and so on. Order of Rotational Symmetry The number of positions in which a figure can be rotated and still appears exactly as it did before the rotation, is called the order of symmetry.
