Usually not.
The angle of incidence is ALWAYS equal to the angle of reflection! This is one of the laws of reflection.
They are always equal.
False .According to laws of reflection, the angle of incidence is always equal to the angle of reflection.
an equilateral triangle has all its angle and sides equal
Yes
Usually not.
No, it does not. But an angle and the angle opposite it are always equal.

The angle of incidence and the angle of reflection are related in the sense that the two angles are always the same. They are always equal.
False .According to laws of reflection, the angle of incidence is always equal to the angle of reflection.
equal to 180°
right angle
an equilateral triangle has all its angle and sides equal
I disagree with the last response. It is implied that the angle you are speaking of is the angle between the x-axis and the vector (this conventionally where the angle of a vector is always measured from). The function you are asking about is the sine function. previous answer: This question is incorrect, first of all you have to tell the angle between vector and what other thing is formed?
