Angle Command

Angle[ <Vector>, <Vector> ]

Returns the angle between two vectors (between 0° and 360°).

Example:

Angle[Vector[(1, 1)], Vector[(2, 5)]] yields 23.2°.

Angle[ <Line>, <Line> ]

Returns the angle between the direction vectors of two lines (between 0° and 360°).

Example:

Angle[y = x + 2, y = 2x + 3] yields 18.44°.

Angle[ <Point>, <Apex>, <Point> ]

Returns the angle which is defined by the points (between 0° and 360°).

Example:

Angle[(1, 1), (1, 4), (4, 2)] yields 56.31°.

Angle[ <Point>, <Apex>, <Angle> ]

Returns the angle of size α drawn from point with apex.

Note: The point Rotate[A, α, B] is created as well.

Angle[ <Conic> ]

Returns the angle of twist of a conic section’s major axis (see command Axes) .

Angle[ <Vector> ]

Returns the angle between the x‐axis and given vector.

Angle[ <Point> ]

Returns the angle between the x‐axis and the position vector of the given point.

Angle[ <Number> ]

Converts the number into an angle (result between 0 and 2pi).

Angle[ <Polygon> ]

Creates all angles of a polygon in mathematically positive orientation (i.e., counter clockwise).

Note: If the polygon was created in counter clockwise orientation, you get the interior angles. If the polygon was created in clockwise orientation, you get the exterior angles.

Note: See also Angle and Angle with Given Size tools .
