  Angle - Wikipedia, the free encyclopedia
Angles provide a means of expressing the difference in slope between two rays meeting at a vertex without the need to explicitly define the slopes of the two rays.
Since the circumference of a circle is proportional to its radius, and an arc in an angle is a fixed fraction of the circumference, the measure of the angle is independent of the size of the circle.
The angle between a line and a curve (mixed angle) or between two intersecting curves (curvilinear angle) is defined to be the angle between the tangents at the point of intersection.

 Adjustable measuring device - Patent 6105268
The prior art devices which are capable of measuring inner angles generally cannot be extended beyond 180 degrees because of the limited span of the measuring arc used.
The range of inner and outer angles which can be measured is from angles substantially less than 90 degrees to angles substantially greater than 90 degrees, and is determined by the span of the measuring arc and its two arc sections.
The measure of the angle outer corner between surfaces 66 and 68 illustrated as being about 112 degrees, is determined by adding the angle indicated by the measurement marking 26 to 180 degrees, since the first segment 12 is in line and parallel with the first extending member 20.

The inner surface may be also corrugated (if possible while preventing snow and frost from accumulating) to prevent diffracted waves from traveling along the surface into the aperture.
For a given half angle, the inner shield's length is made long enough so that, even at the minimum telescope elevation of 50°, the radiation diffracted by the outer shield will never enter the window directly (equivalently, so that the window will never see the outer shield).
However, a longer inner shield requires a taller outer shield for hiding the inner shield from the ground (when the telescope is vertical) and therefore a wider outer shield.

The inner control loop 21 also comprises a compensation circuit 25, a step generator 26, or motor driver 26, that is adapted to generate step commands, and a gimbal drive 27 that produces a desired gimbal angle signal that drives the gimbal 13.
The inner control loop 21 is a servo loop that controls the antenna 11 to a commanded orientation with respect to the spacecraft 12.
As before, the inner control loop 21b may also include a notch filter 28 or additional phase lead to stabilize flexible modes in the gimbal 13 or antenna 11, and may be implemented with either analog or digital electronics, or a microprocessor.

The horizontal axis indicates Alpha(Outer), which is the angle between the centreline of the car, and the direction of travel of the outer-wheelprint.
A steering geometry that generates large dynamic-toe-out angles will cause the inner-wheel of the car to develop a larger steer-angle, and slip-angle, than the outer-wheel, whenever a large steering movement is made, and the car is still travelling straight-ahead (see the "Static-Toe" section, and Figure 2).
An important observation to be made of Figures 5, 6, and 7 is the size of the angle Alpha(T) between the steer-arm and the track-rod, and its effect on the dynamic-toe curve.

 Pitch angle distribution of energetic electrons in the inner radiation belt
The pitch angle distribution of these electrons usually showed a drastic change as the satellite passed from the slot region to the inner belt near the magnetic equator.
When the satellite moved into the center of the inner belt (point (B) in Figure 1(a)), the form of the pitch angle distribution (Figure 2(b)) was completely reversed, that is, it showed a typical dumbbell type distribution.
The result are shown in Figure 1(b) where the distribution of the average pitch angle anisotropy indices n during the period of 1994 are plotted on the orbital plane.

 Wikinfo | Polygon
A polygon (from the Greek poly, for "many", and gwnos, for "angle") is a closed planar path composed of a finite number of straight line segments.
The sum of the inner angles of a simple n-gon is (n-2)π radians (or (n-2)180°), and the inner angle of a regular n-gon is (n-2)π/n radians (or (n-2)180°/n).
The reasoning also applies if some inner angles are more than 180°: going clockwise around, it means that one sometime turns left instead of right, which is counted as a negative amount one turns.

is the 72° angle between the horizontal foliation and the kink band boundaries measured externally.
The inner foliation angle decreases as the kink angle increases until the zone is symmetric (unless the Zone dip is divisible by 3, the zone dip and inner angle may differ by one or two degrees).
The zone dip and inner angle edit fields will reset themselves to 90° and all the other fields will be reset to zero.

radians, the point on the sector’s arc to which the inner wall of the corridor is tangent is described by the coordinate (cos t, sin t) and a distance of one unit.
Now a second vector extends from the tip of the first vector, where the inner wall is tangent to the sector’s arc, to the arc of the undetermined region currently tangent to the outer corridor wall, at an angle perpendicular to the first vector.

The Theta value is the radian angle of the spotlight's inner cone, and the Phi value is the angle for the outer cone of light.
Light is brightest in the inner cone and isn't present outside the outer cone, with light intensity attenuating between the two areas.
This value is equal to the cosine of the angle between the two vectors, and serves as an indicator of the vertex's position that can be compared to the light's cone angles to determine where the vertex might lie in the inner or outer cones.

 Kinematic Models
The inner component is not observed north of the galaxy, presumably because the split lines cannot be resolved at a sufficiently small radius due to the intervening inclined disk of the galaxy.
This is required to explain the lack of a sharp velocity gradient in the low-velocity component (LVC) at a radius of 350 pc, as is observed in the high-velocity component (HVC).
While the observed velocities of the HVC could be duplicated with smaller cone opening angles and a larger inclination, the low velocities of the LVC require small inclination angles.

The other two angles can combine with one of the angles in the inner pentagon to make a straight line.
This means that angle A is 180° - ((180° - p) + (180° - q)), which is equal to p + q - 180° (where p and q are the appropriate angles in the pentagon).
Similar reasoning can be applied to B, C, D and E, and so if we label the inner angle of the pentagon as p, q, r, s and t, then the total of A, B, C, D and E is found by 2(p+q+r+s+t) - 900°.
