That depends on what type of shape it is as for example a triangle can only have 1 right angle of 90 degrees.
acute angle obtuse angle right angle reflex angle a straight angle
You use the right angle next to an acute angle perhaps and you see that when a angle is closer together it is an acute angle and if it is spread apart or farther apart from a right angle it is an obtuse angle. If the angle is a straight line and doesn't look bent like a right angle it is a straight angle.
A reflex angle
Complementary angle to which angle?
By controlling the amount of gate current !!
The calculations for changing the firing angle in SCR is K = 1 [π − α + 1 sin(2α )]
The SCR turns on based on gate voltage. The firing angle will depend on the point in the AC cycle where the gate voltage is where you want it, so the firing angle is a function of circuit design, not of the SCR.
The minimum angle of a regular polygon would be 60 degrees.
There is no minimum value for the cosecant function.
The angle of minimum deviation in a diffraction experiment is the angle at which the diffracted light rays are the most spread out, resulting in the best separation of the different colors. It is typically smaller than the angle of the first diffraction minimum to achieve maximum dispersion.
f a line is drawn parallel to the angle of incidence axis (X-axis), it cuts the graph at two points, showing that there are two values of angle of incidence for an angle of deviation. However, at the point of angle of minimum deviation, the line will be tangent to the curve showing that for minimum angle of deviation there is only one angle of incidence.
The angle of deviation of light passing through a prism decreases as the angle of incidence increases until it reaches a minimum value called the minimum deviation angle. After this point, as the angle of incidence continues to increase, the angle of deviation starts to increase again due to factors such as total internal reflection within the prism.
Changing the firing angle affects the conduction angle of the AC voltage waveform supplied to the load in AC-DC converters like controlled rectifiers. By altering the firing angle, the average output voltage and hence the power delivered to the load can be controlled, affecting the speed or intensity of the load, like in motor control applications.
The firing delay angle is the point in the AC cycle at which a thyristor starts conducting. By adjusting this angle, the power factor of the system can be controlled as it affects the balance between real power and reactive power. A smaller firing delay angle can improve the power factor by reducing the phase difference between voltage and current.
94.5 degrees
Angle between coupler link and output link for a given crank angle is called transmission angle, it is maximum when crank angle is 180 degree and minimum when crank angle is 0 degree
