what is magnitude of a angle...?

Answer:
The magnitude of the angle is the "amount of rotation" that separates the two rays, and can be measured by considering the length of circular arc swept out when one ray is rotated about the vertex to coincide with the other Magnitude. A vector is always the hypotenuse of the right angled triangle formed by its x, y and z components. The magnitude of a vector is found by using Pythagoras' Theorem. The magnitude is always a positive number !1a : great size or extent cannot wage a war of such magnitude— A. N. Whitehead the magnitude of an earthquake. b(1) : spatial quality : size able to operate only over distances of very small magnitude— G. W. Gray.magnitude is described in simple words as “distance or quantity”. It shows the direction or size that is absolute or relative in which an object moves in the sense of motion. It is used to describe the size or extent of something. Generally, in physics, magnitude relates to distance or quantity.
Step-by-step explanation:
It is the amount of rotation through which one of the arms must be rotated about vertex to bring it to the position of the other.
Draw an angle of 50
o
with the help of a protractor. Draw a ray bisecting this angle.
ans. With the help of a protractor draw ∠BAC=50
o
With A as centre and any convenient radius, draw an arc cutting AB and AC at Q and P respectively
With centre P and radius more than half PQ, draw an arc.
With centre Q and the same radius as before, draw another arc, cutting the prviosly drawn arc at a point
Draw SA and produce is to any point R
Thus ray AR bisects angle ∠BAC
Magnitude of angle simply signifies the amount of rotation a ray or anything has gone through . And you also include the sign of rotation then we can get two values which can be of anti clockwise and clockwise rotation . For example if array is rotated 50° in anticlockwise direction which generally say its magnitude is +50° but if it is rotated clockwise we say its direction is -50°
